I didn't know that most of the Divergent came from Abnegation, and I don't know why that would be.
Wait. You didn't, Tris? Hm. That's funny, because I knew, which (since yours is the only POV in the book) means someone must have mentioned it at some point, and you heard about it. Sounds like kind of an important little fact to be forgetting, doesn't it?
Oh. But I guess you've been too busy acting like a hormonal, whiny pig to remember any of the little important things.
.....Actually, aren't pigs supposed to be smart? Then maybe I overestimated you. My bad.
