You know what I will admit that is probably the one good thing coming out of this. I was actually worried what would happen once Flash Forward ended but I will admit having him be a big part of the upcoming events is somewhat good to know he won't be forgotten right away.
Who knows maybe we will get lucky and its not Wally has gone Parallax, but that he is seeing some soon to be threat but everyone thinks he is going Parallax after Heroes in Crisis.
