Insider here.
Seth Rollins has real heat backstage. So much so that his wife has had to politic on his behalf. That is why she was given the night off. She was booked to face Trish in the ring, but Trish did a solo promo instead. Rewrite only hours before showtime.
Seth has a delusional view of his where his career should be. He has admittedly not gotten along with others due to his own jealousy. In other words, he has a bad attitude and he feels very entitled, but he does love professional wrestling.
Recently overheard a convo that went, "He will never main WM again without be repackaged and dropping that ridiculous fucking laugh." referring to Seth. So, word is, if Riddle can get over with our reintroducing him as a serious character, Rollins will be given the same treatment after Summer Slam. He would be injured at SS. Leave for 9 months, then be repackaged as a shield like version of Rollins, slated for a return at WM40. As of right now, he's right where he's supposed to be.
