MEMPHIS, Tenn. — He’s baaaaaack. One month after escaping WWE medical officials and going on the lam, Dean Ambrose has returned from his walkabout and is ready for some payback. In fact, the self-dubbed “ugly stepchild” of WWE staged a literal sit-in until The Authority presented Seth Rollins for further punishment. What he got was John Cena, who similarly wanted a piece of Mr. Money in the Bank. Ambrose wasn’t exactly OK with splitting his prize down the middle and seemed more than ready to throw down with the Cenation leader as well. The Authority’s attempt to restore order led Cena and Ambrose to take matters into their own hands and chase Rollins through the bowels of the arena, until he commandeered a civilian’s car and sped away from his pursuers.
