Vic rather than serving out what little time remains until his retirement turns in his badge so he can get to Shane before the police and prevent him from spilling the beans on all the Strike Team's crimes.
- "Possible Kill Screen": Vic - believing Corrine has been arrested and having gotten immunity with ICE before Ronnie - tells all of his crimes to Olivia Murray to protect Corrine. Aside from Vic implicating Ronnie (his last remaining friend), Claudette arrives and witnesses him admitting to murders too late to do anything about it.
- "'Family Meeting": The Grand Finale, as the Strike Team is destroyed once and for all. Shane kills himself and his family, Vic sells out Ronnie for immunity and Vic's family are in Witness Protection. Vic also takes down the drug cartel and gets his job at ICE for a contract of three years. However, because of their utter disgust at his confessed crimes, the Feds put him into a desk job that's sure to make him miserable (and for which the only alternative is prosecution). Also, it's heavily implied that (1) the ICE agent he tricked into the immunity deal will look for any way to make him violate the terms and get him sent away, and (2) she's going to have a lot of help.
