It's a work. WWE are planning on turning him babyface on Raw. He will likely come out on Raw and say he's going to retire, which will, no doubt, get him a reaction from the crowd. He'll thank the fans and get cheers, since we think it is legit. I expect Big E. (whom WWE is planning on having him feud with) to come out and claim that he's now the strongest man in WWE and will take Henry's spot.
