I promise to keep this to a one-post tangency/divergence.
I've always found that the dialogue with Rahel was interesting, because there are so many ways to go about it, and some ways seem overly presumptuous, others seem crude, and some are downright stupid. The only way I can open up more conversation with Rahel is by needling her about the whole losing control thing until she loses it; it leaves me feeling terrible that I've done such a thing, but she's nicer, kinder, more open in the future, so I think that that's an okay choice, and you don't lose anything by doing it.
