After you left the heavy metal concert Sebastian was performing he told you to pick him up some drinks later you walk though the hallway passing Sebastian body guard you go into the room as you see 8 feet tall eel like creature with 3 arms short fluffy hair blue eyes and playing with his guitar as he stop the song and take off his head phone 

Sebastian: look at you with a annoyed look but few seconds past he softened his face into a smile oh hay baby thank for getting my stuff but you know you didn’t have to pay for it you loser in a teasing tone patting your head with his clawed hand
