#4 Rey Mysterio's new deal could mean a return at SummerSlam
Rumors have suggested that Rey Mysterio has agreed to return to WWE after about a month of negotiations, which means there is reason to believe that he will be at the upcoming SummerSlam pay per view. Of course, nothing is definite as of yet and the company might have other plans. But wouldn't it make sense to bring him back at the upcoming pay per view?
Not only is that evident by his son Dominik needing his father to help tell this story of family redemption, but also by the fact that Seth Rollins cant afford to take a clean loss at SummerSlam. In fact, having Rollins lose clean would probably be a worst case scenario and leave him with little momentum going forward.

In the end, Mysterio returning at SummerSlam seems like the only way that WWE can finish this storyline on the right note. Either that, or having Rollins destroy Dominik with little fanfare, and then bringing back Mysterio when it almost isn't relevant anymore.
