WWE WrestleMania 39: 20 Things That Must Happen
6. Edge Goes Brood Style
Major sources say Gangrel will return to WWE at 'Mania 39. Nobody really knows what kind of part he'll play on the show, but it'd make sense if he was there for Edge's entrance pre-Hell In A Cell bout. After all, Finn Bálor will assume his 'Demon' guise again, so a Brood reunion seems plausible to counteract that.
You also know what that means: BUCKETS OF BLOOD.
WWE won't have Edge or Finn bleed (unless it's hardway and "accidental") inside the cage, but they could circumvent that by bringing stage plasma aplenty to the party. Even if they don't, and blood doesn't play a major role in the Cell match, then simply having Edge/Gangrel (sans Christian, obviously) go Brood style would be enough.
This could be Edge's final hurrah on the biggest stage of WWE's year, and he'll want to go out with a bang. Paying homage to his humble beginnings in the promotion would be a fitting way to cap off an unbelievable career.
