The Mass Effect 1 "romances" were actually far better done than the second game's... at least in the first it was semi-believable and had some progression to it. The Mass Effect 2 ones consist only of like one conversation (in which Shepard gives 'em the creepo smile) and then the sex-with-clothes cutscene at the end. Both games have the off-looking female, though (Ashley and Miranda). Jack's probably the best bet... I'm betting she'll have clothes and hair for ME3 since she'll have been out of prison for a while by then. And we know her face isn't going to be ****ed up (could still happen to Tali!).
