So I just ended Mass Effect 2 on the model finish. I did all the devotion missions/ship upgrades; but, I was not at all able to increase Jack's faith back behind the quarrel with Miranda. So I didn't use her for any of the squad picks on the last level and now when I'm walking about the Normandy I don't observe her in the basement. I don't memorize seeing her die, so where is she? Did she just leave, or did she die and I just didn't see it? I recognize she didn't die when the ship was being attacked, as on the final fight I had her holding back the aerials with everybody else.
