Meltdown is the twenty first episode in the eight season of the television series JAG and the second part of the pilot for its spin-off NCIS with Ice Queen (episode) being the first part. This episode also marks the final appearances of NCIS Special Agents Vivian Blackadder and Don Dobbs respectively.
The NCIS team continue investigating the death of Lieutenant Loren Singer as Harmon Rabb struggles to come to terms with the fact that he may be facing life imprisonment and it appears to be a simple case but Anthony DiNozzo, the second-in-command and senior agent of the NCIS Major Case Response Team soon discovers that someone else may be responsible. As the case goes on, NCIS also find themselves racing against the clock to stop a terrorist from carrying out another terrorist attack on an unidentified American ship and at a port but one team member's obsession with avenging a dead relative at all costs may jeopardize the operation and end the agent's career all at once...
While Abby and Major McBurney are discussing the photos in her lab, "Frozen" by Collide is heard playing in the background.
The song playing when both the JAG lawyers come to the lab with Gibbs to get the results from the tag in the hat is "Monochrome" by Collide.
This episode also marks the final appearance of Special Agent Vivian Blackadder played by Robyn Lively. Due to overwhelmingly negative feedback from test audiences in regards to her, Blackadder was written out of the show and Lively was also released from her contact. As a result, the character Caitlin Todd was created and she was also Blackadder's replacement in terms of being both an NCIS Special Agent and Tony DiNozzo's partner. When NCIS first aired as a solo series in October 2003, Blackadder was shown to have been removed from the show altogether to this day no reason has been given as to where she ended up although many suspect she could have been fired from NCIS or simply returned to the FBI.
On the Region 2 DVD, the recap of the previous episode was removed and as such, the episode cuts to the opening credits instead.
