Huge episode involving both Fusco and Carter and where their relationship will go after this. Bombshell is that Fusco confesses to Carter about his shady past and that he has "killed people". Of course this isn't going to sit well with Carter. "Once a dirty Cop, always a dirty Cop". That's the mantra she lives by. So, with the Feds closing in on Fusco and the location of where he buried his ex-partner's body, Carter has a decision to make. Does she help him or let him twist in the wind. Of couse she helps him. But it's the reveal at the end when it's implied that Bear the Dog is the one that led her to the burial site to move the body.

The final scene also implies that the Machine is now infected with the computer virus as the signal goes haywire. This could have been the Season Finale. It sure felt like one. But, we still have two more episodes for this season. Yay!! The other half of the episode was about Finch and Reese's "failed" mission in that they didn't save the man from poisoning. So, the rest of the episode is about exacting retribution against the man that poisoned him and giving him one last chance to confront him. It was great. Payback is a b*tch indeed.
