Oh, I think Draco would run away from Bellatrix too--I was more thinking of an alternate universe where Bellatrix hadn't spent the past however many years in Azkaban etc. and they knew each other etc.

I think Draco's often the most logical person too--I'm not saying he strikes me as crazy now, but wondering if this is something JKR would do to him. I mean, the times where Elkins says he seems crazy (and I'd agree these are the times when he seems the most...overexcited) are the times when scary stuff is happening. If he was all calm and confident in those scenes I'd be more worried he was a sociopath. So I do agree with her that in those scenes he doesn't seem like Mr. Evil who's just pleased his Dark Lord's plans are going well...he's more like, "This is good. I think. But it's scary as hell. Dammit, why do my father's plans always have to freak me out!!"

So I'm almost wondering if his sanity isn't something that would be used against him later. Like, he's just not crazy when it comes to this stuff-he's scared of Voldemort, animals with big teeth, Dementors...all very reasonable things to be scared of. But remember this is a book by somebody who thinks courage is the most important virtue to have...so I don't know. In order to have a storyline that ended in madness Draco would have to start out sane, which he does start out as. Being a regular, sane kid surrounded by crazy people could have a bad effect!
