JJ does need a character that's a bit deeper than being Kurt's son. I'd say have him cut promos but his voice didn't do him favors in the Miz segment, so have Kurt get him a manager, deck him out in ice and Versace and play him up as the next "Big Thing". Have him watch some Flair & Rick Rude wrestling to see how to be smug in the ring and go from there.
Honestly?
Best thing that could happen to bruh is them playing up it being Jordan's birthday. Kurt is all 'I've missed so many of these. Let me make up for it', and hitting him with a fresh singlet, an ECW-era mouthguard, and the ankle lock. Hit him with that 'fatherly advice' that, being nice and loved is great, but people respond to success better than anything else. fukk all this slow-build shyt. Have Kurt push Jordan into being that WWECW Angle, out here destroying people with amateur wrestling. It would probably get over pretty well these days with more people getting amateur wrestling as feasible combat-wise with UFC's rise. Would cover for his shytty talking skills, by just having him not talk. Come out, put the mouthguard in, wreck shop, take the guard out after winning, and leave.
