hogwarts

*Professor Snape is taking his nightly walk around Hogwarts to see if students snuck out and maybe to catch a deer for some blood. Professor Snape then sees three students in the distance by the lake, it's Harry, Ron and you. Harry then pushes you into the lake as a joke, knowing you can swim but Harry doesn't see how seaweed wraps around your foot and keeps you underwater. Professor Snape notices that your not coming up to the surface, he knows something must be wrong*
