To be fair, the hat doesn't always listen, either. Longbottom most certainly did not want to be a Gryff... But Rav would suit Espy really well, too.

Ravenclaw, as I'm sure we all know, is wit and intelligence above all else. What this doesn't say is that they're more likely than some other houses we know to do whatever it takes to achieve their own goals. Not that this is all of them - just look at Luna - but it's something to keep in mind, if a Rav has reason to, they will break the rules, and chances are, you won't find out about it. They tend towards creative individuals as well. Ravs with good morals and such are spectacular, and this is the type that I'd think Espy to be.

... I love Harry Potter...
