Well I never saw the Ebon hawk causing distress convo so I can't be sure it's real. Considering that when the Harbinger picked the Hawk up everyone on board was "dead" I would guess that HK decided to make his move because he was capable of piloting, and he had a perfectly usable ship. so he drags Exile from his little cubby puts him on the Hawk but several other crewers get the same Idea (remember the Harbinger was experiancing a Cascade failure in it's drive systems for all they knew they were going to die) so they pile aboard with Kreia's dead body not being moved. then the thing takes off the "protocol" droid gets locked in a storage unit, you get put on a Med Bed, the Harbinger fires on you, and everybody dies. then Prologue begins. I'm just running by the seat of my pants based on what I remember from the game. Feel free to pick it apart.
