Carlito has been a whiny little bitch most of his stay in the W.W.E, and Primo is only even still on the Main Roster in my opinion, because of Carlito. This could go one of two ways.
See, the Colons are meant to be Brothers, or some shit - obviously related, right? I really don't give a damn to know how. So why not just push them as the next Holly Cousins? They fought each other as much as they fought other people as a team. But they still did both, and did it good enough to get them over.
Carlito could make yet another piss-poor attempt at a Single's push, but it never fails that each time he tries.. either an injury stops him, or the pure fact that he sucks does one.
This will be a horrible ending for Primo, especially if they break the team apart completely. Primo will fall worse than Carlito, because he's only even remotely entertaining because he's related TO Carlito. I think if anything, they turned the wrong Colon heel in this event. I guess Night of Champions will look to be Kofi Kingston against Carlito, perhaps? Toss Evan Bourne and Big Show in the mix.. and you have a sure-fire clusterfuck of stupidity.
