Maybe he wasn't BAD, bad... maybe he was just CONFUSED at how he thought this was going to play out. Harry likes girls but I don't think he'd be super forward about it. Wasn't he a total mess about Cho for the longest time in the books and couldn't even talk to her normally, much less make any sort of move without having a near heart attack?

Hermione's so easy to appeal to. Just study in front of her.

"Oi, Harry, want to cause mischief or some shit?"
"No thanks Ron. I actually want to study for our Potions class tonight. You know how that mean old professor Snape gets. If only there were [i][b]SOMEONE, SOMEONE WHO BELIEVES HOUSE ELVES DESERVE A VOICE, TO STUDY WITH[/b][/i]~~~"

Boom, she's wet.
