Russian Featurette (possible Spoilers)

First post... I was watching this Russian featurette on Prometheus and it contained some footage I hadn't seen before... http://www.youtube.com/watch?v=WCtOGmNHshw&feature=fvsr But as I was watching this I noticed something new in footage I had seen before but missed. It's where David is in the middle of the astral projection and you can see something moving towards him from the right. Here's a screengrab because the shot is only on screen for 1/4 of a second (probably to mask the fact that someone else besides David is present). [URL=http://www.imagebam.com/image/516c0a190637387] From other behind the scenes footage I've seen shots of David standing on the set in the center while someone else pulls up a big chair so it's possible that other person is the one who gets up and walks to David in the astral projection. More ominous would be that it's an Engineer or mutant looking to off him. I played that video sequence over and over trying to tell whether it's a human or something else and it's just too short to tell definitively one way or another. But I would think it probably was just another human. I figure this scene occurs early on before all the really bad stuff starts happening. Then again, this is the spot where David meets his doom.
