[SPLIT LIP]

Maybe so many people mistook what was clearly just a distortion of his existing helmet for a new one, they decided to redo the shot and just have him move his head more? (Or, because it was never intended to be any kind of forshadowing, and it's just a result of them reshooting to have lockseeds instead of locks)

Needless to say, I have never felt more vindicated from a half second of minor movement. I knew it wasn't a new armour, it was just the rippley floor, and this proved it. No forshadowing, no meaning. Just a trick of the light exposed for what it is so they could show lock seeds instead of locks.
