Season 1 had one of the best twists in the series, with Nina Myers being the traitor. The writers did a remarkable job with her being suspected early on...only to be dismissed as a suspect. The viewer cancels her out as the traitor...and then BAM! The phone call with Drazen.
I'm very sure you'll enjoy season 2. A number of very shocking things happen. And continue to expect the unexpected...because that's what this show is all about! That's one of the many reasons I love it.
And as for the "Bauer family", well...you'll just have to wait and see.
