Mark - read up on the links Dena posted for a pretty comprehensive rundown of each episode.
Anyway - I have some really big question marks about S3 which drive me nuts, because even at this point they aren't solidly answered! They're still filming S3 and by the time the premier airs they'll still have about 10-12 more episodes to shoot, so they can adjust midway through the season based on fan feedback.
Bottom line: Nina, Mandy, Max, and the guy Max was talking to on the phone (the guy eating breakfast, I think), NEED to be involved. The whole notion of that common thread throughout the seasons that this higher-up organization has been behind it all is very, very exciting.
If anyone has seen the deleted scenes on the S2 DVD, they've noticed that there was a scene where Nina is supposed to join Max on the boat right at the very end. That in itself provides hope that they have that kind of thought in mind.
Remember the end of S1? "If you kill me, you won't know who I work for. You think I work for the Drazen's, but I don't."
And what the HELL did Jack whisper to Nina right after he escaped her holding him hostage in S2? I've been reading on Fox's message boards and it's just as much a mystery to them as well. Funny thing is, there are always one or two people who have the inside track and post info, but this is one topic that wasn't ever resolved. I really hope it plays a part in this season. If you go back and watch that scene, you can't help but sense the deliberateness of it. Something's gotta come of it.
