What are you people talking about? Wiping MJ's mind isn't exactly going to make Pete's life easier, it'll make things worse. She'll be an even easier target for pricks to get at Pete. If she doesn't know who Pete is, why should she trust or listen to anything he has to say? Besides, if there's going to be any mind-erasing shinanigans going on, they might as well go the whole 9 yards and set minds back a couple months before the whole CW bs started.
I'm definately looking foward to this just for the simple fact that Tony prickface stark is gonna get owned.
