(S04E08) I love the multiple ways the title of this episode works: No Exit refers on the surface, and most basic level, to the scenario in which the characters find themselves. Many characters on both sides of the promicin issue wake up suddenly at NTAC when they started out asleep at home. Both sides think the other has brought them there for nefarious purposes, and they begin preparing to defend themselves when they realize that, like the Hotel California, they can't leave. So, of course, being bright people, they immediately start trying different scenarios that will help them leave despite the fact that there appears to be no exit.
