Trying to fit all the pieces of the puzzle

Ok, Lets see if we can figure out how the blue guy gets into the ship and how that fits into the rest of the story. First trip to the temple. They release the red globes, they discover the head and bring it back. David takes an ampule and brings it back. Holloway takes off his helmet, disturbs an ampule and gets infected. They race a storm back to the ship, examine the head, David cracked open the black goo juice bottle and Shaw and Holloway wrestle...:) They need more info, so back we go, but before they do vickers tells them if they go they are all going to die. Trip 2) The goo Hooloway disturbed has been busy and has created the cobra hugger, it attacks Milburn, all hell breaks lose, Mohawk guy gets a face meltdown, David wonders off to the star chamber and wakes up the SJ blue guy, A merc freaks, shoots him the SJ kills Ford and the merk, The team run for their collective lives to get out. They leave David. They get to the ship and find Vickers outside waiting for them. Holloway is now in full transformation and gets burned up by vickers. mohawk guy goes berzerk in the landing garage. Mr Weyland makes his appearance with his mercs and kill mohawk. Shaw is distraught over losing Holloway but deduces that something is wrong with her and in an exam realizes she is hosting an organism, she has cuddles taken out and placed in a holding chamber. she recovers realizes they left David, tells janek they are not leaving and trys to go back for him. She gets chased back by the blue guy who wants his ampule back, as shaw and the blue guy battle in the ship cuddles gets lose and wipes out some of the crew, Shaw escapes as the SJ and cuddles do battle. Shaw realizes that Weyland with davids help is flying the juggernaut she knows that the black goo is poison and would devastate the earth, she tells Janek to ram it. Vickers escapes and with Shaw try to load up in the escape bay to travel back to earth. Cuddles escaped as well, Vickers kills it but is infected and dies. Shaw goes into hyper sleep and is found by the company. Thats my thought, or i could just lie and say i saw the fox sneak peak last night.
