Whenever I watch ET or something like that, they show them shooting movies or tv shows or whatever. It seems to me there are times when they aren't needed on the set, and they go to their dressing room or something to do whatever...I read that the "Friends" cast used to play poker a lot during downtime. Perhaps that is why Carmine has some downtime when he is filming, perhaps they are shooting a scene with Mac and Flack, and he's not needed at the moment, but needs to stay close by for his next scene. My point? Perhaps that was why he sent more e-mails during the scene, he was able to read them when he had spare time between shooting scenes. So when the new season starts, perhaps he will spend some of his downtime on the computer. Right now he is probably busy doing whatever, enjoying his last days of freedom before going back to work, so maybe he will get to yours soon. Not sure but that is what I think, about why he may reply more often during the season.
