Vito not only the only one ?

Who does tony mean when he tells carlo ( during his "promotion") that lets face it vitos not the only one to be gay ?!?

i really dont remember Tony saying that. All i remember is Tony yelling at Carlo"Maybe you should start sucking cock cause vito brought in 3 times what you do with construction!"

He calls carlo into the bing office to make him head of vitos old construction. They start going back and forth about vito and thats how tony ends the convo. Check it out.
