OMG, Claire got out, but then.....Oh, my poor, lovely Mac, my heart just breaks for him. Poor Claire. I wonder if she went back to help others, or was killed when the second plane hit? Like by falling debris? Some people on the spoiler discussion thread are bitching about her possibly going back in, if that was the case, but personally I think that would fit, she * was* married to Mac after all, she would want to help. But, oh, how sad.
On a lighter note, I *love* how in the flashback, Mac looks like he did in s1, the hair, the tie....i am wordless at Gary's amazing acting in that clip, the fear and horror in his eyes and voice....
