Why wouldn’t Jimmy want Jey to win the title so he can face him for it?
It's armchair booking, so don't take this seriously, but I was watching tonight thinking that instead of Jimmy costing Jey, you have him and maybe Solo help Jey go over on Gunther and win the title. Jey is rightfully confused leading up to the next Smackdown, where they reveal that they were sent by The Rock, unbeknownst to Roman, to get Jey back in with the Bloodline and family. Jey is pissed, sees thru Rock's manipulation, and refuses to rejoin setting up him and Jimmy.
In one instance, you set up the Uso storyline and the underlying tension between Rock and Roman as we advance into Mania.
