I was also disappointed with the last episode. Got to hand it to Chase though. That axe action was pretty good. Didn't see that one coming until I realized the clamp was built on to the unit and wasn't a handcuff.
I'll miss Sherry Palmer and the Prez. I don't see him coming back. If they couldn't have him have significant involvement in the main plot then what good is he being a civilian? (Mr. Ex-President, your golf balls have been tampered with. We'll need Jack Bauer and CTU to examine them for bounciness.)
I actually missed the dialogue after the vial blowup in the fridge due to a phone call. What was being called in to Jack on his cell phone at the very end?
