The Orions took Jihadi Johns DNA seconds before he was killed. They gave him a different body and used his DNA and they placed him immediately on another planet. They allowed him to remember who he was and what he did when he lived on planet Earth. They put him on a planet where you have to fight to live. You have to fight to find food and water and you have to hide from animals that will attack. He is out in the cold and this is his punishment for how he lived his life and the bad deeds he did.
