The Miz made his return to WWE. As noted, he’s been backstage at Raw for the past few weeks and creative was just waiting for an idea for his return.
Chris Jericho also made his return to WWE on Raw. He faced off with Miz for a couple of minutes, the lights went out, then the Wyatt Family attacked him so he’s already in a feud with Bray Wyatt. Jericho was talked about for a return around WrestleMania but he turned them down at that time.
