The "right" thing to do is purely an opinion. I'm sure the guy wishes he had the disc back, but honestly he probably already thinks he'll never get it back. If I were you I would get to know him better, and once you know him on a more personal level you can judge for yourself if you think he deserves it back.. that way if you're playing with him and he starts screaming at some kids... you can just sit back and think "Haha.. nice.. i got a 11x FB".
