Does this mean something to anyone else?
And everything I said makes perfect sense.
EDIT: I think I get what you mean-- Henry could have gone into the vent, gotten out on the other side, and just left?
If this is what you mean, it actually doesn't make sense, as the vent, as far as we know, leads between the dome room and the kitchen/armory/pantry where henry and kate entered it (season 2, episode 2,3,&18). And the dome room was also sealed off, as the finale this season shows. So he couldn't have just magically gotten out, at least not until after the doors went back up, at which point the button is pushed or not.
And further, I don't think henry could have gotten far enough away from the effects of the pulse or whatever. Locke sent him into the vent with like 30 seconds left on the timer. Assuming Gale knew what the button did, he CERTAINLY would not have risked it. Gale would have done exactly what he did - Plant doubt into the button-pushers' minds, and let them push it once your dead or gone.
But I still don't think Gale had any idea what not pushing it would do. The event seems too cataclysmic, and there's been no word that Gale knew there was a failsafe. While I know this last point is debatable, I find it hard to believe even an Other would actively pursue the detonation of that Electromagnetic pulse, or whatnot. (Note: Carlton Cuse was quoted after the finale saying that if the failsafe wasnt activated, the world would have collapsed in on itself.)
And finally, there's been no indication that they test those they feel are good (at least not pre-capture), so I don't know why he would have been testing Locke.
