Trying to make sense of the Jimmy interference, without the story being "circular" with guys coming in and out of the bloodline which IMO would really hurt the storyline. (then again some were concerned after the Sami match, Cody match and that never happened)
I suspect Jimmy is acting on his own, and has a beef with all of them now.
My guess is that within 2-4 months we will have a 4-Way match between Roman/Jey/Jimmy/Solo. And perhaps one 3-way without Roman before that. Essentially the finality of the bloodline is every single one of them has their own agenda and becomes their own man moving forward into 2024.
Obviously they will also get an Uso/Uso match out of it, but in the scenario above they try to delay that one as much as they can - perhaps at WM40.
