#2 Becoming Husky Harris once again
Wyatt has said time and again that he did not feel the Husky Harris character. But then, maybe it's time to return to his old shell, so as to shake things up on RAW quite significantly. There's always the possibility that he's leading the new pool of NXT talent to RAW.
In doing so, he could form the new Nexus. And it makes a lot more sense for Husky Harris from the Nexus to lead the group, than for Bray Wyatt. This is the only storyline payoff that would justify him returning to the Husky Harris character once again.
Could Husky Harris become an even bigger character with this invasion angle than Bray Wyatt had become? I personally cannot see it, but as Vince McMahon keeps mentioning, it's always good to shake things up on WWE television.
