Producer Howard Gordon says "it is a little bit of a reset, it is really promising at the same time." The "reset" will take place due to the events that will take place in the second season finale. The season has received some complaints about the storyline with Brody's daughter as well certain plot twists.
Gordon answered a big question on everyone's minds - will Damien Lewis be back? "He's alive so of course he'll be back. One of the great challenges of next [season] is how he'll be back. But there's no doubt that he will be back."
