I find it hilarious and sad that people can't figure out why Enzo is pissed.
His knows his own limits, he knows how his small stature means nothing, he has the talent of the gab and that's it. He knows it. So the moment you split up the team he is without any purpose in the company, his WWE career is done.
He existed to get Cass over and that's it. He knew it and of course it's hard to accept. His promo at the PPV was so good and so telling, it really is all over for him. He reached his dream but he has to try and move on and reach for his new ones.
The internet uses the term bitter and anger like they understand it.
