if you haven't seen the latest AOS episode turn back now, question has spoilers :F
So AOS season 4 episode 6, johnny blaze GR is referred to as the devil by robbie. Does that mean the devil took over blazes body? Or does robbie think it was the devil but it was just johnny blaze?
Also, isn't robbies GR a serial killer spirit (not the spirit of vengeance)? So how did blaze just transfer his powers over to robbie?
