Alliances are formed in threes on an all-new GLEE, airing Tuesday, March 4 at 8 p.m. ET/PT on FOX.

As graduation approaches, Tina, Blaine and Sam band together to hold a senior "lock-in" at school, hoping to savor their last chance at hanging out together. But their plans are thwarted when Becky joins unexpectedly.

Meanwhile, in New York, Elliot (guest star Adam Lambert) is stuck in the middle between Rachel and Santana's feud.
