Rory's bitching at Mack for not telling him, a nurse, that he was getting green mutations, and then they hear the horrible death screams of Alaya and run down there. "We have to be better than this!" he screams at his daughter, which nobody would ever say, and Ambrose protests once again that she honestly thought even Alaya's brainless awfulness had a limit, and she would have stopped once Alaya gave in. Which is clearly and obviously true, and sort of the point. Because now that you're bitching about it, what you're really saying is that you burnt our bargaining chip, which is I think in some ways worse. Alaya had no intrinsic value as a living being because she was choosing not to act like a living being, at which point you can do whatever you want with her in my opinion. I don't like zealots and I don't like terrorists, and insofar as she had any sort of personality I guess she was both. Now she's dead, so fuck it.
But either way, it's not really Ambrose's problem, because it was a mistake. She became more and more human the longer Alaya talked, and I don't mean that in the cynical nasty way this show so often does: If they'd made it all about her anger, it would be her fault, but the actress is so good and her lines were so specifically rational that the whole thing falls apart, and you've just got everybody taking turns getting on the high horse about it. Which, hilariously, is exactly what's going to happen downstairs too: One woman takes it too far and becomes emblematic of everything wrong with her race, while a bunch of weak men bitch and complain and tell her how awful she is, without doing a damn thing to fix the problem.
Anyway, Rory's begging Alaya to tell him how to fix her, and she gets all messianic about how she's glad to die because helter skelter, and he tries a limp Doctor impression -- "You're not dying. I'm not going to let you, not today!" -- that falls flat because he's not the Doctor, and even the Doctor sounds like a twat half the time when he does that crap. Girlfriend groans out her last breath and everybody stares at Ambrose realizing she just killed Earth. And it sucks because you can't even be happy Alaya finally died, because you got Restac downstairs being twice as annoying without being scary or cool at all.
