Johnathan over here is the reason Zimain went to jail,as he was wrongly accused for his crimes,and got out free.
Johnathan is the reason to Bonsu's robotic parts too,as they escaped just in time before they were murdered,like their father.
Bonsu's mother was killed by Bonsu's brother,Evan,after escaping the asylum he was held in.
Johnathan beloved not Satan,and performed rituals daily. He sacrificed Bonsu's father,in order to have a response from Satan. That didn't work,so he planned on doing another sa addict with Bonsu,but they escaped just in time.
