After Hours is the 17th episode of NCIS Season 13 and also the 299th episode of the entire NCIS series.
The NCIS team find their plans being interrupted when they discover errors in a seemingly cut and dried case that has apparently been closed. As the team work to find out what's gone wrong in the case, McGee and Delilah argue over the importance of not discussing work during dinner while DiNozzo bores his date with shop talk.
- The date that DiNozzo entered is later revealed to have stolen DiNozzo's NCIS ID badge and counterfeiting it to at least three actors as part of a scam, thus framing DiNozzo.
