Barba, Carisi, and Nick all are working undercover at a gay bar when the entire operation goes wrong. It was originally going to be Carisi and Nick only but the suspect decided to change their kidnapping to three instead of two people. They went after men who could pass straight but were gay in secret. This worked well for them because all three of them were straight. Last minute change in the standard prey almost blew the entire thing. Finn wasn't available and the only other man who was close enough to the squad was ADA Barba. Thankfully he agreed when Liv asked him to go UC.
