I missed the explanation for why Lauren and Carlin killed themselves. I understand everything else in the episode, just not the suicides. If anybody can explain that for me, that'd be awesome. Thanks.
I believe they killed themselves because they didn't want to be part of their fathers plan, or that they couldn't cope with the thought of the apocalypse.
What I don't understand is why they killed themselves the way they did. Why all the symbols and lining up of the lamp posts and whatnots.
I guess I need to see the episode again some day, there's a good chance i missed something important.
