If Dominik Mysterio had tried to defy Nia Jax that night when she attacked Rhea Ripley and landed on her ribs, he would've probably gotten the same punishment Rhea got. He didn't have the courage to save Rhea that night.
Rhea ribs were not injured she took a little time off to sell the storyline injury, she was with her real life boyfriend buddy murphy. So stop making it out that Nia hurt her when she didn't.
I have never liked Nia as a wrestler. She is incredibly predictable and slow. It’s almost as if she just stands in one place and just tries to seat people like flies.
