I had an Idea of having him become the new professor Zoom. I think that Wally should grow up with Barry and then later leave like Dick Grayson did with Batman. During the time he leaves he starts struggling in life. He might have his girlfriend die, or something of that nature. Later he becomes angry and doesn't have enough money to get by, so he starts stealing from banks. The public blames Barry and believe he is the one staling the money. Barry tries to get to the bottom of the situation, and finds Wally. Barry doesn't know it's him but starts fighting him, he notice he has similar powers and moves he does. He also begins to realize that this speedsters faster than him....later in the couple issues he might find out it's Wally or something. Anyways that's my idea of what they can do for Wally in the new 52

What do you guys think?
