When the alarm went off, Ren broke his bed for the second time. A large, freaked out pink bear was at fault, this time. The alarm was loud. Very loud. Ren heard people in the hall and moved to join them, this time turning into a mouse to get under the door, then into a bird to fly near the ceiling, out of the way of trampling feet. It was easy and freeing to start transforming now after the cast came off.
After a while, Ren realized it was a fire alarm, not an attack on the school, but well, he would be naked if he transformed back into himself. He really did need to get those unstable clothes or whatever, but he didn't want to spend the money. So he just flew out of the building with everyone else, flying in lazy circles, enjoying the feeling. He hadn't transformed into anything that flew in a while.
