I'm imagining some sort of rocket propulsion spell which, without careful timing, would result in the subject slamming nose first into a stone wall. Considering Hogwarts's track record, this'd be the least of their problems.

And I just bared my Harry Potter-nerd status for the world to see.

She could be in his room. She'd just have to figure out the riddle, bring her Griffindor blanket, and we know that at least the Griffindor room allows girls into the boy's dormitory and that it dates back to the founders so presumably Ravenclaw's dormitories would work the same. Easy!

Or, well, maybe he used a broom.

lol Considering the room itself is reds and golds (curtains, pillows, etc), I don't think she's in the Ravenclaw room :P

Does it say something about that in the books? I'm only starting the Goblet of fire, but I remember one of the other books saying Hermione came into the boys room, but they did say to get out, she just didn't care.

I can't remember which book it was, but one time Ron tried to go to Hermione's room, and the stairs turned into a slide and made him slide back to the common room, and Hermione explained that it was a security system the founders set up to protect the girl's dormitory to keep boys out. The same does not apply to the boy's dormitory, and Ron commented on the unfairness of it. So, girls can go to the boy's rooms, but boys can't go to the girl's. It might be in Half-Blood Prince, which is why you haven't encountered it yet.

However, I think a sufficiently clever student could figure out a loophole in those arrangements… especially a Ravenclaw.
