Being Bad is the 2nd episode of NCIS Season 14 and the 308th episode of the entire NCIS series.
While investigating a death that took place at a reunion at Quantico, the NCIS team uncover a bomb plot which soon leads them to a long-running theft ring while Torres and Quinn adjust to life as members of Gibbs's team which also includes new sitting arrangements and the bullpen's structure also changing in the process.
- Torres and Quinn begin their tenure as the new members of the main NCIS Major Case Response Team.
- Palmer and Abby meet Quinn in person for the first time.
