RE:
Here's what i remember: Curtis had been caught by the bad guys and when we see them, he's "passed out" and they are taking him out to kill him, when he "comes to", kills the guys and is stuck on the floor becuase he needs an access card to get out. Meanwhile, Jack gets info from Paul and is heading to the building where Curtis is which happens to be where the override is, too, and one of the terrorists is working on it to be sure the other reactors melt down. Tony got the info on the building from Berous' mother. Berous is still at CTU, although we haven't seen him. Curtis and Jack find the override, the terrorist gets away and Jack goes after him. Edgar talks Curtis through the technical stuff for the override and the other reactors stand down. Meanwhile, Mya is having severe problems and Erin does what she can in the situation to help her out. Just as the reactors are standing down, Erin is called to the sick bay, can't come right away, but when she gets there, she finds that Mya has killed herself. That's when we see scenes from next week's show where Tony has interim command of CTU.
