(Season 1, Episode 12) "Then what is the point of staying calm?" - Janet, after Joe told her to stay calm, they were coming to get them

OK, there were a few things in this next-to-last episode that I just didn't buy, and I'm not talking about Ulrich's head exploding.

Many plot developments just didn't ring true and seemed a bit rushed. Ulrich saying he was going to go ahead with the experiment but then trying to help the group escape. Blackham getting beaten up near the vault and everyone immediately assuming he was killed even though the security video only showed him getting beaten up.
