#3 The Rock is surprised by the anti-Roman crowd

By the time Royal Rumble 2015 rolled around, the fans had had enough of Roman Reigns, after realizing that WWE was shoving him down their throats.
After Bryan was eliminated early on in the match, the fans didn't care one bit and booed the entire locker room out of the building. The end saw Roman Reigns being manhandled by The Big Show and Kane, with The Rock himself coming out to his cousin's aid.

Rock's surprise appearance did get a loud cheer, but as soon as Reigns won the match by eliminating Rusev last, the boos resumed immediately. As The Rock held Reigns' hand high, he heard the entire arena booing him, and it could be clearly seen that The Rock wasn't too thrilled with the reception.
WWE tried to bring in The Rock to raise Reigns' hand so that the boos would stop, but the plan backfired and The Rock was visibly pissed off. He was reportedly pissed off at WWE too, for going ahead with the plan.
