Not really, dude, she just got out of jail, and I don't see Draco doing anything but going 'AHHHH CONVICT.' I mean, Lucius wouldn't be having them round for tea, would they?

Oh, man. By that reasoning, Draco wouldn't sleep with nobody in the books except maybe Pansy.

But I do agree that closeness to Bellatrix could shock Draco into maturity, and, well, logic? Because I don't think he's logical at all. His courses of action (and schemes) are all rather silly and poorly planned.
