24 Season Finale tonight

I cannot wait to get home from work tonight and watch the season finale of 24.  As long as it doesn't take a turn for the worst, this will be my second favorite season behind season 5, and it appears that quite a few of the events from Season 5 have had a HUGE impact on this season.  I just want to see Jack healthy again and hope that Kim tells him about his granddaughter, and I'd like to see something besides the stem cell stuff be what cures Jack.  I'm also as curious as anyone else to see why Tony has been on both sides of the fence so much this year. I not only want to know why he did it, but why he destroyed the CIP device earlier this season, why did he warn Jack about the White House Attack, and why did he blow up the rockets at Starkwood if he were the bad guy?  We'll know all the answers in less than 12 hours.
