BREAKING NEWS.......the tentacle

Ive just watched the IMAX trailer frame by frame and at about 12 seconds you see a suited arm.......with......wait for it........the tail of our tentacled or smooth chestburster or what ever you want disappearing into the suit. At first i thought it was the pods around the SJ chair. But no....its moving and appears to be articulated at an elbow. This could lead to the "Cut it off, cut it off" quote. It also appears to be covered in dark blotches on its skin.....and heres the cruncher.....it appears to have a spine........squids dont have spines. This defo has a spine. Next im going to examin the hologram of the SJ ship to see if the scans picked up anything below the SJ chair. Watch this space lol.....cos no one can hear you scream in it.
