>>14099113Blame Cena.
Enzo kissed Cena's ass in a pleasing fashion backstage and Cena went to bat and wasted a good chunk of his banked political favors getting Enzo a huge push. Vince went along with it but only because he wanted to push Big Cass with Enzo has his hype man.
When Cena fucked off for good as a full timer, Enzo was screwed. Vince started demanding he read promos the writing team wrote with ZERO improv which Enzo refused. Which was all the excuse Hunter needed to get Vince to break up him and Cass and bury Enzo deader than Zach Ryder and kick him out of the company.
