The nice thing about a panel is if by chance a question like that does come up, then my guess would be that another one of the cast would answer it and they would likely have that discussion prior to the panel. It's also possible that Josh won't be as vocal about the show as he has been in the past. However, having said that, the actual affair in the show is kind of old news and both Cole and Alison have remarried, so there may be other subjects discussed.
