Dominik is also “in the mix” as told to us by a member of the writing staff close to the situation. It was explicitly mentioned that that are “too many variables,” and the term “drowning” was also used during one point in the conversation.
Vince McMahon has options for SummerSlam. Dominik will be “in the mix,” but no mention of his father was made. It’s unknown how Mysterio signing new deal could cause another huge creative change. It’s highly likely that would be the case.
Nothing is locked down, except for what has been announced. They are playing with some ideas. Seth Rollins vs Dominik is being considered as well as a tag team match where Dominik would team with Aleister Black against Rollins and Murphy. “All options are being discussed” at this juncture.
Another idea for SummerSlam is Seth Rollins vs Kevin Owens. It was told to us that WrestleMania re-match is a strong contender.
