Good call indeed! Well, I didn't really noticed this picture (I didn't look at all of them specifically), so I weren't trying to figure out which ones were what, but it is interesting!
Maggie: I have some doubts about this one... Since every pictures are supposed to be Matt-related, this one is being Nathan-Peter related... It's true Matt was there, too, but somehow managed to shoot himself!

(by the way, is there any picture of him receiving the bullets he shots at Sylar? Just wondering!). So anyway, this scene with Peter and Nathan not being Matt-related, it is unlikely that this is the scene... Moreover, it seems like an indoor thing...
Hey, now that I think about it... It's crazy but... What if it's a scene from the very beginning of season 3? When Matt where running for Peter, who just happened to got teleported in Jesse? The shadow behind the guy in yellow shirt could be Future-Peter, the guy in yellow shirt being Peter getting teleported into Jesse, and the guy turning the corner is Matt about to find Future-Peter, thinking it's Present-Peter? Not the best theory, I know, but it kinda fits the painting...
Also, can anyone shows me the ''future-future'' paintings? The one where Matt is happy with a girl and a baby, and the other one where Matt hold the (apparently) same girl, apparently dead? This girl, in my memory, looked so much like Daphne, which I thought was weird, yet interesting! I just wanna look at them again, to see if it could be someone else, or find any sort of clue about the future... Thanks in advance!
