Pearl will literally fight to stay on the ship and try to help fix it. She's put enough into this ship that she is either going to save it or go down with it unless someone drags her off kicking and screaming. She probably doesn't have that much longer to live anyway, so hey, why not?

Meanwhile, Luci will evacuate without any trouble unless she's really needed to fly the ship and someone talks her into it. Steph can help escort people to the Empress or Liminal Space as necessary.
