I can't be the only one who knows that...
No comment usually means yes (but I'm not gonna talk about it)? Because honestly, no way in Hell would JC say that if he weren't dating her. He would have said NO just like he did in the past about Tara (and just like he said about the rumor that she lives with him). JC/Eva haters need to stop trying to come up with reasons why no comment actually meant no. It's silly.
