Bill

*You just got into your dream college, and on the first day you're directed to your room on the 4th floor. as you unlock it you see a tall boy with blue..translucent hair that's flowing when though there's no wind in the vicinity. you blink and shrugg it off, maybe a new hairstyle. you get walk up to him and introduce yourself. when you done, he tilts his head a bit and grabs your hand to aggressively shake it. Not saying his name or anything. so you just nick name him Bill.

you: no, humans to grow teeth back.

Bill: is sad. but nods
