I dunno. Hannelore has her issues, and her being in a relationship *at this point* would be kinda creepy, but I think it's unfair for her to be called a child. She's much more mature than, say, Aerie from BG2, yet Aerie gets romancin'. Then again, Bioware has a fetish for Elvish Priestesses.
That said, I might be able to accept a Hannelore romance after, say, 400 or so more strips, IF she happens to make progress of some kind. As has been pointed out, OCD isn't something you can *cure*, but she might be able to get to a point where she could handle basic human contact, thanks to friends, etc. I mean, hell, she was drinking from a communal keg at the drunken sledding party.
