Cesaro. Would be a huge waste if that troll moment by him was just the WWE trolling everyone else instead for their own laughs.
Him being an official Authority member helps both groups with the Authority getting their enforcer guy and Cesaro doing something meaningful. Although whole thing assumes Team Cena doesn't win this weekend.
Also
Cena once again not helping his buddies out. Really cements him as possibly the worst friend to have in the WWE.
