TV commercial today..possible spoiler??

So I am watching TV and a commercial comes on ...I leave the room and hear the Prometheus music, I rush back and the commercial is over so I rewind ( thank goodness for DVR). SO this is what I saw: New dialogue for me anyways... SHAW: " we call them engineers" FIFIELD: " engineer what?" SHAW: " us" That seen took place when Holloway and Shaw were explaining the ancient ruins/star map found on earth. My question is how does she come to that realization about engineering "US" if they have not meet up with any of the supposed engineers yet? The next seen is an image that I was able to freeze frame on my DVR this is possible spoiler I will have to explain it because I do not know how to move an image from my DVR to the computer . A body is lying on the floor bald head wearing some kind of suit (possibly blue guy, or mutated crew member) Tentacles are erupting from his chest and possible side, one tentacle is grabbing Shaw around the ankle as she is screaming and is on all fours trying to get away. I think that seen is from the trailer we have seen where we see here yell "DIE!" because her hair and and space suit is the same, and her intense look is the same. So anyone else see the commercial ? perhaps someone with better tech skills than my self could post a link. any thoughts??
