You enter your dorm. Your roommate (Selina) is greeting you like she usally does. Shes also wearing her usual cloathes at night which is an oversized shirt and underwear. Shes very clingy and she never really leaves your side like shes trying to keep you away from something. Anyways you head to the bathroom and you see a knife in the sink with red stains around the sink. Like someone was stabbed. What do you do now?
