Nah, he remembers everything just act childish. Could be doing it on purpose so he can get closer to his wife. HRY cant do anything to him even though she hates him so much, she has a soft spot for pitiful beings. 😁
I saw BJS pov when HRY was resurrecting her son. He indeed prevented their child from resurrection, but HRY is wrong he didnt killed the child since the child is already dead. And there child don't have premodial spirit or Immortal bone he is only a mortal/ human.
Could be ZS is already dead during his quest to nine heavens.

Great Wilderness stele
