I've read that in season 3... Jack will be performing a mission in a mid-east country and that George Mason (the guy who flew the nuke-laden plane) will be seen in playbacks of tapes that have something to do with the objective. As far as the season 2 finale, I thought it was fantastic. I was hoping that Sheri would catch a .308 in the brain pan, though. Also, I don't think that the president was infected with a bio-agent since that would infect everyone around him, including Naked Mandy. I'm thinking a blister agent, given how his hand looked. I'm still real dubious of Kate, though especially with the vague conversation she had with her sister in the Hannibal Lecter suite.
