Remember when Rex told on Prometheus [that his wife left him] twice? And nothing happened, because no one cares about Rex except to laugh at what a pussy he's become? And remember when he started acting like Tommy Tantillo and couldn't defend his "opinions" when someone disagreed with him except to cry all over the boards? Remember how thoroughly broken Rex is?
Remember when Pro was so butthurt by the accusation, that he went absolutely fucking nuts, and spammed his backlash at Rex across every forum?
That's some serious butthurt. And perhaps a grain of truth in Rex's accusation, that Pro was so broken by it.
