I wasn't targeting you specifically
My take on what we've seen:
When they discover the Juggernaut ship underground, the remaining humans (sans the flight crew, Vickers and perhaps Weyland if he's still alive by then) suit up and go inside it. The scenes we've seen from inside the ship play out - David remains in the control room, activates the holograms and communicates to the others, exploring other parts of the ship, what he's watching.
The surviving engineer is awakened/alerted and he emerges from the only remaining intact cryotube in the controlroom. It could be a sight if he emerges in the scene with the jockey hologram playing and David doesn't realize at first, that there's an actual living engineer approaching him.
David is dealt with, Ford + armed guy and the others. Shaw is the only one who makes it out before the ship takes of. Cue scene with her running on the surface, alerting the flight crew to stop the Juggernaut at all costs. The collision happens, the Juggernaut crashes and the engineer exits and approaches the lifeboat module now sitting on the ground -> face off with Shaw & possibly Vickers.
Shaw with the axe
might not be her dealing with the engineer (not that there's anything wrong with that image imo) - it could be the tentacle creature as well...
Sorry for the rant and I'm probably wrong about at least 50% of this anyway (we all are I suspect)...
