When Poe experiences a sudden massive increase in inertia (landing after a long fall, crashing in a ship, etc) and maybe a few other sorts of things that would kill him, he teleports. He has no control over this and is unaware he does this, just he wakes up far away from wherever he was about to die assuming he ejected or had some other perfectly logical intervention happen.

He also doesn't seem to think it's at all weird that he wakes up bollock naked.

(if anyone wants to take this a step further and turn it into a full-on Forever AU/Crossover, be my guest ;D)
