[b]EVERYONE! I GOT IT! On the 1st level when you are approved guilty once you are on the conveyor belt,go through the opening door with full Flow and when right before the gate closes, quickly go under it. A cinematic will appear after the blocks rise and you run to the light. It is VERY HARD to do. I found it out when I noticed that all of the other gates, when you go into the next room are all OPEN after you go into the next room.
i tried that about a million times, it doesn't work. i have full flow but when i try to turn back i bounce against an invisible wall when the gate is still coming down.
if i would think logically, i would notice that the name of the flair for finishing the main ending is "ending" and the one for releasing the prisoners was "freedom". they both have something to do with their names. so this means the way of unlocking the flair "defiance" has something to do with the word. it would fit perfectly with n353456's post, but this seems to be impossible to do. so what else could it be?
