I didn't watch the whole thing, saw the shot at 43 seconds, but then when they were like "did you see it", "no", "watch closely" I'm expecting it to be one of those stupid videos where they draw you in and freak the crap out of you with loud noises and some nasty looking picture. I don't need that kind of stress

OK, turned my volume down and watched it again. yeah, some weird thing was there, but looks like an artifact of compression.
