This whole Steen/Generico angle from last night makes no sense at all from whatever way you look at it. If you look at it ignoring all non-wwe stuff, some random new guy just attacked the guy that won the title. They have no history that you've seen whatsoever. If you look at it acknowledging their ROH history, its two guys that had an absolute blood feud for 2 years and the last time you saw them hated each other. Then they reunite for like a minute and Steen turns again? I guess? If you look at it as, everybody knows that they're really friends behind the scene, and all of those hellacious matches are just pro wrestling angles, then who cares about this angle because it also is just a wrestling angle and they're friends behind the scenes. It makes no sense.
It makes tons of sense. They specifically told the story of how:
a) Owens and Zayn were good friends from before.
b) Owens had to watch while all his friends made it into WWE before him
c) His best friend Zayn won the NXT title at the show he was debuting at.
Connect the dots and BAM, motivation for why he'd turn on his best friend out of jealousy. He kills two birds with one stone, elevating himself to a title shot immediately and getting revenge on the person who "made it" while he couldn't. You can rag on a lot of storylines in WWE, but this one is pretty airtight and well explained by the announcers to boot.
