PROS: *Can make you a fake limb. *If you're dying, he more than likely can save you. *He likes picking at things. So you can get a good head massage.
CONS: *Probably gonna wake up, forget who you are and stab you. *Likely to hallucinate and accuse you of something stupid. *Cant cook OR drive. *All his limbs are FAKE!! *May throw his limbs at you in rage. *His body fluid is all acid. no kisses. he also needs a special toilet. *Hates being touched unless explicitly asked
Honestly if you asked him out in character he'd just walk away.
