>>211442687He's dead. He couldn't swim so he couldn't escape the facility and the Empire won't spare one of the ringleaders of this mess (he used his real name and the surviving crew of the control room could identify him anyway).
In fact they probably killed ALL the evaded men they caught and even those that didn't escape to make sure no one in the next batch would believe an evasion was possible. It's safer and simpler for the Empire.
So yeah, there is no way he isn't dead.
