She battles Aliens and survives until the very end - in which her and David depart to find the origins of the Engineer race and ultimately to get the answers they've been looking for all this time.
Michael plays "David", a robot synthetic (a main character) on board the Prometheus venturing out into space. David is secretive and manipulative. He is the reason Holloway gets infected and we believe he is also the reason the Engineer reacts so violently towards the crew upon waking him... We think David says something to upset him.

He unfortunately dies a very horrific death as the Hammerpede breaks his arm, crawls into his suit and begins to burrow itself down his throat - killing him from the inside out.
Logan will be playing the role of "Holloway" in Prometheus - the other lead scientist on the expedition. Holloway is also in a relationship with Shaw and is infected mid-way through the film with Alien bio-fromer technology which later begins to mutate him - but not before he passes on some of the mutant DNA to Shaw in a passionate scene involving the two of them. The result of this is an Alien fetus which later grows up to be the horrific, proto-Facehugger, "Trilobite"!

But his inclusion into Prometheus has officially tied Prometheus into the Alien timeline.
No word yet as to what is to become of the Yutani Corporation, which eventually joins forced with WEYLAND to form the famous WEYLAND-YUTANI CORPORATION from ALIENS. We may or may not see reference to this joining in Prometheus.
