I’ve been stalking following Matt Giraud through his twitter account for some time now, when I finally realized something after looking through several pictures he posted on his tweets.
Where is his forehead mole? 
Did he have it surgically removed or is it simply a case of bad camera lighting? I’m thinking it’s the former.
ETA: I did not photoshop this picture. If you want proof, go check out Matt’s twitter account. The photos he posted are somewhere there.
I think it was a cyst because it seems like it got bigger and smaller during the course of the show. He didn’t have it when he auditioned (see pic here http://www.rickey.org/?p=11148). Sometimes, a cyst will go away by itself, but he could have had it lanced or removed.
Oh, yeah, it wasn’t there before (and now)
Maybe that’s why people were calling that thing on his forehead a zit, because it comes and it goes. LOL
Someone mentioned that it was a wen. IDK
