Idk, I've not seen her hair dyed. I have seen G4's dyed and at the same time as JW's. There's also the factor that AW, I see, as having a difficult time of being very speedy, and I think the murders were done very fast. If we look at G4, right after the murders, he's not as hefty as he was at the time of the arrests, nor in his Ls photo. I just get a very odd vibe off of G4. Could be nothing, could be something. JW, I think, would follow his lead (or anyone's lead). I think he's a follower. That theory is subject to change in the next week, day, or hour...
