Shaw creature Vs. the big blue guy.

Shaw escapes the ship as the creature and the big blue guy battle it out. The question is why did the blue guy come on to the ship to start with? Shaw goes back to the Juggernaut looking for David and when she goes she takes a navigation element back with her to the ship. The big blue guy wants it back, and he runs into the creature who has grown a great deal since it was taken out. As those two fight, Weyland and David start the Juggernaut to take it back to earth. Weyland wants the Black goo as an elixir of extended life. Shaw knows it is poison, that it would destroy the earth and Tells Janek to Ram the ship and stop them. She and Vickers live, they escape to the life boat, as they try to get it operational the creature( it kills the SJ and lives through the crash) attacks them, Vickers kills it but she gets infected and dies. Shaw takes off and hypersleeps, and is found and recovered by the company......around the same date that the Sulaco is entering lv426.
