I don't know. But he actually rolled his eyes and said something along the lines of "Yeah, there are always a few Castiel stans around." which I personally felt was incredibly rude.
Even more so considering it was a con that had Misha but neither Jared nor Jensen. So, yes, surprise, you might actually find a few people there whose favourite character is Cas. And who don't feel like keeping that a secret at their one chance to talk to an executive producer who actually has the power to make or at least influence some of the important decisions.
