Timothy "Tim" McGee is a Junior Agent working on Leroy Jethro Gibbs's team. He made his debut appearance in the Season 1 episode Sub Rosa (episode) as an Agent stationed at the Norfolk Naval Base but he also regularly made appearances at NCIS HQ whenever the team called him for help in regards to a case. He was officially transferred from Norfolk to Washington D.C on a permanent basis at the end of the Season 2 premiere episode, See No Evil (episode), becoming the fourth and final member of Gibbs's team and also the Probie.
McGee, under the pen name Thom E. Gemcity, is the author of the Deep Six series. He also uses the pen name for other things such as in "Ignition" he plays a documentary that he had put together about jet packs which was signed Thom E. Gemcity.
His relationship with DiNozzo has jokes going both ways, but with McGee on the receiving end of most of them. He has a strong friendship with Abby. His relationship with Ziva is also a friendly one.
In season eight, a Chinese-born Russian chef pointed out that McGee is of Irish descent because of his last name.
McGee has a younger sister named Sarah McGee. McGee is shown to love his sister very much, even handing in his badge and gun to save her in Twisted Sister (episode). Nothing much is known about his past apart from that prior to being re-assigned to NCIS HQ in Washington D.C, McGee previously worked in Norfolk Naval Base. He has a B.S. in bio-medical engineering from Johns Hopkins University, and an M.S. from MIT in computer forensics.
Originally stationed at the Norfolk Naval Base, McGee had his own office which was full of papers and as such, was difficult to move around in. He usually worked there, spending most of his time going through paperwork but got his first official taste of fieldwork when he was called to the scene where a body had been found in a barrel acid during "Sub Rosa" although he was left with a weak stomach and presumably threw up elsewhere to avoid ruining the crime scene which showed just how unprepared he was.
This prompted him to call in the Major Case Response Team led by Leroy Jethro Gibbs which was in Washington D.C. Gibbs arrived along with Agents Anthony DiNozzo and Caitlin Todd, Medical Examiner Donald Mallard and Medical Examiner Assistant Gerald Jackson to help him in investigating the death.
After the case was solved, McGee returned to his position at Norfolk but made regular appearances during Season 1 as he was often summoned to Washington D.C at Gibbs's request to help them work a case.
In UnSEALed (episode), McGee was first seen at the back of the bullpen at the desk that had a closed-off wall from the rest of the area but in future episodes like Dead Man Talking (episode), he was seen at the unused desk opposite Gibbs's which would later become his own when he permanently joined the team.
He also proved to be extremely helpful in uploading new photos to Gibbs's computer to help him look for the terrorist who had caused a hostage situation in Bête Noire (episode).
In the Season 2 episode, See No Evil (episode), McGee aided the team in regards to the kidnapping of a Navy captain's wife and daughter and at the end of the case, was set to return to Norfolk but Gibbs announced that McGee had been promoted to full-time Field Agent and as such, was now on Gibbs's team. He also claimed the desk he had originally used in "Dead Man Talking" which had belonged to Vivian Blackadder as his own.
As a result, McGee resigned from his former position at the Norfolk Naval Base and permanently transferred to the Navy Yard in Washington D.C where he has remained to this day.
In the Season 9 finale, Till Death Do Us Part (episode), McGee is caught in the bomb blast at NCIS HQ. He caught a shard of glass in his lower abdomen but, after being released from the hospital the following day, was back at work to help catch the terrorist responsible for the bombing.
Although McGee specializes in computers, he has demonstrated other skills such as Boy Scout skills as seen in the Season 6 episode, Hide and Seek (episode) and was shown to be something of an excellent shot in the Season 10 episode, Phoenix (episode).
McGee had an extended relationship with forensics technician Abby Sciuto in season one, but there is no direct reference to their relationship ending. However, despite this, they are still very close and often tease each other about their previous relationship/dates (sexual jokes, suggestive comments, etc.), and in some instances Abby has shown jealousy of attention women have given McGee. In contrast to Tony DiNozzo, McGee has had few relationships, or possible ones, almost all of which have begun and ended in the same episode.
In Season 5, McGee has issues with a girl who stole his heart and his credit, when he asks for help from Abby she tells him "I love you McGee and that should be enough", which hints that Abby still has feelings for McGee.
When in stressful or uncomfortable situations, as seen in the episode "Grace Period", while trying to deal with the death of a friend, McGee will often retreat to the forensics lab for reassurance from Abby.
McGee owns a dog called Jethro, that was accused of murdering a Petty Officer during the Season 5 episode, "Dog Tags". Abby looked after him and named him after Gibbs, but because her landlord wouldn't let her have a dog in her apartment, she forced McGee to take him much to his dismay as the dog had attacked McGee at the beginning of "Dog Tags", forcing him to shoot it in the leg.
Aside from Gibbs's basement, McGee's home has been shown in the most number of episodes of all the series's characters. Various characters have been inside at one point or another; namely Tony DiNozzo, Ziva David, Caitlin Todd, Sarah McGee, Abby Sciuto and Abby's previous boyfriend/stalker, Mikel.
At the end of Season 8, however there is a very tender moment between the two of them and McGee tells Abby 'If something ever happened to you I would..." which indicates that he still has feelings for Abby and worries about her while also giving the hint that he cares and wants to protect her.
Leroy Jethro Gibbs
McGee lives in awe of Gibbs, and like the rest of Gibbs's team he is very loyal to him. They have a father/son relationship, as evidenced by the episodes "Probie," when Gibbs actively seeks to protect McGee from the Metro PD who are set on charging him with a crime, and "Twisted Sister". During the first season, Tony complains to Kate that Tim gets a pat on the back when he does something for Gibbs, while Tony gets slapped on the head. Gibbs is often confused by McGee's answers to questions, which typically involve technical computer language. Gibbs also gives McGee tests to give him more confidence. In the episode 'Witness,' Gibbs assigns a case to McGee and lets him make calls, and in 'Caged,' Gibbs gives McGee the job of getting a serial killer into confess (although that may have been because DiNozzo and Ziva were vying for the assignment, and Gibbs simply wanted to teach them a lesson).
Despite his great respect for Gibbs, McGee is not afraid to stand up to him as shown when Gibbs strongly interrogated McGee's grandmother. McGee is confident to overrule Gibbs and take over the interrogation. After their conversation, Gibbs is seen smiling, impressed by McGee.
McGee and Tony have an older brother/younger brother relationship. Tony antagonizes McGee, calls him names (such as McGoo and McGeek), and generally annoys him. This initially started off as newbie hazing but has grown into more. When Gibbs left the team at the end of Season 3 and Tony took over, Tony made him a senior field agent, showing his trust and respect in McGee. Tony may call McGee names, but he refuses to allow anyone outside the team to do so. In "Guilty Pleasure", when Tony befriends Philip McCadden, he soon becomes annoyed and hurt by McCadden continuously joking on McGee.
In the episode 'Probie' Tony went to McGee's apartment to cheer him up after he accidentally shot and killed a cop, even going to the point of telling him an embarrassing story about himself to make McGee feel better. In the episode "Frame Up" McGee shows he cares for Tony by going to visit him while he was in jail. In 'Witch Hunt' the two are driving to a crime scene and Tony tells McGee about the last time he dressed up for Halloween and it ends with the two of them laughing, showing their real relationship.
In Season 2 episode 'The Bone Yard', McGee makes a judgmental comment about Italians and the Mafia, which offends Tony, who is of Italian descent. Tony points that he is 'Italiano', but isn't Mafia material. McGee apologizes, Tony replies 'Prego' and slaps McGee Gibbs-style.
At the beginning of Season 7, Gibbs promotes McGee to be Tony's partner in replacement of Ziva. His junior status is revoked and he becomes a Field Agent. During this time, Tony's respect for McGee grows and, while he still calls him names and antagonizes him, he hasn't called him Probie since the season began and the two have shown to be a lot closer, like when they hang out together after work.
However, Tony does call Ziva a "Probie" in Season 7. He and McGee brought up that Ziva was the Probationary Special Agent to avoiding searching a dumpster while investigating the murder of a former Navy Commander.
Although their working relationship was somewhat short-lived, McGee and Kate worked well together despite Kate having on the team much longer than McGee. They formed a temporary partnership during Dead Man Talking (episode) and again in See No Evil (episode) where McGee who was still not a full-time field Agent was required to have someone accompanying him if he ever went out into the field and while McGee found Kate intimidating, they still managed to get the job done.
- "You've been a naughty boy, Timmy."
- —Ghost Kate talking to McGee while they're in Abby's lab during "Kill Ari Part 1".
Following Kate's death in Twilight (episode), McGee, like the others struggled to cope with her death and while in Abby's lab, he had two images of Kate first wearing a PVC bodysuit similar to Trinity from the Matrix movies and then, her clothing changed to form a single BDSM suit complete with a whip which left McGee stunned and causing him to remark to himself that he was becoming Tony.
- "Why haven't you come down to see me yet? If you peak at the back of my head, it'll just look like I'm asleep. I'm so lonely. I'd even welcome a visit from Tony."
- —Ghost Kate talking to McGee in "Kill Ari Part 2".
However, McGee's third and possible final image of Kate had him seeing her lying in a drawer in the bull-pen where she encouraged him to visit her.
McGee and Ziva have a sister/brother relationship, with Ziva often joining Tony in picking on McGee, but also with the two of them joining up to pick on Tony as well. For example, in the episode Bait, Tim and Ziva asked what movie Tony had gotten an idea from. Ziva goes out of the way to give McGee more confidence in 'Caged,' when Gibbs gives the task of getting a serial killer to confess to a murder to McGee. When Tony asks when was the last time McGee talked a woman into doing anything, Ziva comes to his defence, saying that McGee had asked to borrow her last $10 and she let him. Ziva is protective of McGee in 'Caged', when she and Tony see McGee coming out of the prison and Ziva asks if anyone hurt him, so she could 'kick their ass.'
McGee also goes out of his way to make Ziva feel better after killing a man in 'Jeopardy.' However, McGee is still willing to pull rank on Ziva occasionally. When the team had to search a dumpster at the Naval Academy following the death of a former naval commander, a colleague of Vice Admiral Chase, McGee and DiNozzo forced Ziva to search the dumpster, noting that she was the Probationary Special Agent on the team.
In Baltimore, Ziva says that even if she lost contact with McGee for a couple of years, if someone killed him, she would hunt down and kill his murder because he is not just any partner.
Ducky is one of the few individuals to use McGee's full given name of Timothy as illustrated in the Season 2 episode, See No Evil (episode). As with Abby, Ducky at times adopts a fatherly attitude towards Tim as demonstrated in the Season 4 episode, Smoked (episode) although in the Season 7 episode, Masquerade (episode), McGee made some rude comments about a dead body, drawing Ducky's anger.
Director Leon Vance
In episode 6.07 "Collateral Damage" Gibbs and Director Vance had a discussion about the qualities the ideal NCIS agent should possess. During that discussion, Director Vance told Gibbs that McGee exemplified the model agent, in contrast to Gibbs who prefered agents like DiNozzo. During "Enemies Domestic", McGee was distraught after seeing the extent of Vance's injuries following the explosion.
In Season 2, "See No Evil," it is revealed that McGee has a sister, whom we do not officially meet until Season 4. Her name is Sarah McGee, played by Sean Murray's real life step-sister, Troian Bellisario, executive producer Donald Bellisario's daughter. She first appeared in Season 2's Red Cell and again as a picture on McGee's iPod in Season 3, and once more in Twisted Sister. In 6.19 "Hide and Seek" it is revealed that McGee's father was Navy, although he hasn't been shown in the series to date.
In season nine viewers were introduced to McGee's paternal grandmother, Penelope Langston portrayed by actress, Lily Tomlin. According to Tomlin's comments regarding the role, Tomlin stated that Penelope Langston is a scientist whose husband, retired from the U.S. Navy as an Admiral and is deceased.
Penelope Langston insists that her grandson call her "Penny." During the 1960's she worked for the Tellus Group on the Annex Principle, a bio-engineering project resulting in her involvement in a murder investigation related to the project as documented in The Penelope's Papers. She was also stated to be a comfort to McGee during his childhood years, as his father often did not show love for his son. In the same episode, it is revealed that he has not spoken to his father for nearly seven years since he joined Gibbs's team.
McGee, being the most junior agent on the team, is the butt of many jokes and has a variety of nicknames that have developed over his time as part of the major case squad. DiNozzo is the main creator of these nicknames, the most common being Probie. The term evolves into a term of endearment, as explained by Gibbs when he asks McGee to guess what his first partner still calls him. In Season 5 the nicknames becoming more frequent, creative and topical. DiNozzo usually uses the "Mc" of McGee's name to create the link, although he is not the only one to play the game. Gibbs himself has been known to refer to McGee as Elf Lord due to a character McGee uses in an MMORPG.
Other names include: McGeek, McGoo, McNerd, McMuse (used by DiNozzo when playing pranks on McGee for "inspiration"), McGoogle, McGoggle, McTardy (used by DiNozzo when McGee is late), McCheat, McZero (used by DiNozzo, McGee is conducting a massive file transfer and explains it's all in binary, "ones and zeroes", DiNozzo clarifies that he is the ones and McGee is the zeroes and follows this up later in the conversation by calling him McZero), McGruff (after McGee is attacked by a dog) and various other nicknames.
- Prior to appearing in NCIS, Murray previously starred in JAG, NCIS's parent series playing the role of Danny Walden, a teenager regularly causing trouble for his mother's boyfriend, A.J Chegwidden.

- During Season 1, Murray was credited under "Guest Starring" but in the Season 2 episode, "See No Evil", he was officially added to the opening credits, coming in fifth just after Pauley Perette and before David McCallum. This makes both Murray, Cote de Pablo who plays Ziva David, former cast member Lauren Holly who played Jenny Shepard and now Brian Dietzen (Jimmy Palmer) the only known people who were both originally credited from "Guest Stars" to join the main cast although it should be noted that Dietzen who had been credited as "Guest Starring" and "Also Starring" was finally added as a series regular in Season Ten despite having appeared in the series for nearly ten years.

- In addition to being left-handed, McGee has been seen using the mouse of his computer with his right hand, suggesting that like Caitlin Todd, he may be ambidextrous.
