I saw it coming during the episode:
When Deb was talking to the shrink and saying she was just going to have a talk with him...I told my son, "She's going to find him killing Travis". She knew he was at the church. I should have seen it coming when he said he had plans for the church anyway.
I'm glad I was right, it makes me less bothered by the incest angle that the show was going in.
Well, it isn't really incest, though. At least there was that.
well, it is, taboo-wise.
the incest taboo isn't about genetics, but upbringing. (if you're not breeding, there's no reason to worry about the genetics).
if you meet someone in adulthood, fall in love, fuck, and then find out you're father and daughter or brother and sister or whatever, that's 'not really incest' in the societal sense (i.e., if microscopes and computers didn't exist, there would be no problem). studies have shown that people, related or not, raised as siblings, develop the incest taboo, the idea that it's inappropriate to think about them as a potential mate, so, it's kinda amusing to think that Deb has her own little pathology, just like her "brother"
