If all your crew dies then you do as well.
That's actually not true. I sent Morinth with Chakwas, they both were fine, but Shepard died at the end, I was like Wut? But no, you have to be with one loyal squadmate when you're running away.
Oh and I love Noveria, so many possibilities. Not just on the main station, but also where everyone is locked away. If I remember correctly there is the rude asari or the human that blocks your way depending on how you play. It's one of my favorite hub.
I would usually scam the hanar, and make the Krogan kill him. I hate those jelly fishes
