I'm sorry I just think that we need more to go on but all what happened provided he's slowly making his way up my suspect list
and about chad... Assuming he's not playing dumb, he can't be call of duty, link, halo, mario, kirby and I still think that mo was falco which would leave the chad to be marth, meta-knight, pikachu, or battlefield (if you want to add falco to the list then ok) 3/4 (or 4/5) chance of being a goodie
