Big Brother 9: Is the house playing pranks on Josh, or is it a returning houseguest?

Last night we had not one, but TWO instances where someone in a blue "luchador" style wrestling mask spooked Josh, from behind the mirrors. Adam was close enough to see the second one, but so far it's just Josh who's getting scared.





What the hell is going on behind the mirror? Are they setting up for some kind of special April Fool's day on Tuesday? Could it be a past houseguest coming back to haunt them? Only one way to find out, subscribe to the 24/7 feeds, watch After Dark, catch the show on CBS.
