This isn't an au but it's still some jekyllhyde shit

There's a clatter upstairs in Bella's room. Some jerk's come in through the window. And apparently he's making a mess of things, judging by the noises coming from it. A great, whining roar rings out, "Bella!!"

If and when she decides to actually go into her room, whether it's immediately to see what the hell's going on or later to go to bed, she'll find Hyde sprawled out face down on her bed. Squirming plenty.
