Aha! I was right, sort of. Battery operated was key. "Small" doesn't mean much, since any battery operated device (not directly attached to a generator) is relatively small. I still think had the flashlight been on during the blast it would have been knocked out of service too.
The show is becoming more and more unbelievable though. They talked of......waiting for the effects of the EMP device to subside.... It was a burst of electromagnetic energy for crying out loud. It's not as if there would be a lingering "fog" or anything. Any effect would be essentially instantaneous. The way they showed the lights going out in the skyscrapers.....slowly, one at a time. It would be more like - poof, lights out.
Also, why would anyone in their right mind want to work at CTU? Jeez, none of those people get along. Particularly the women folk. And how realistic is that, in the middle of a disaster, the one computer lady with the dark hair and cool scar on her lip (not very good with names, sorry) would be worried about personnel issues? .....I want two pay grade raises, my record cleared, etc.
Since the show seems to be degenerating into a simple soap opera, here's what I think will happen: check out Secretary Heller. Bossy, argumentative, wears a ton of make-up? I think it will turn out that he is actually Secretary HellerINA. A woman. And Jack's long lost mother. Which then of course means that Jack and Audrey are really brother and sister. Ewe. Although since Audrey seems to be the only woman character who can get along with anybody else on the show.......maybe it will turn out that she is actually a guy? Oh no! That means she/he and Jack are actually BROTHERS. Gack. Anyway, eventually Secretary Hellerina will eventually become President, as he is fourth in line behind the Vice-president, Speaker of the House, and Martha Stewart.
Just guessing, but like the battery theory, I bet I'm right.....
