Is Tom going to go back to his home realm? His mother could go to a psychic asking about her son, the psychic would say something like ‘Thomas Edward Perkinjay! I summon thee! Spirit come forth!’ Or something like that. But it would mean he would hear his name and could follow the summons from the abyss… I think.
Anyway just a funny idea. Give his mom and the psychic (could be fake or real doesn’t matter since all Tom needs is his name said) a heart attack seeing a demon pop out of thin air. Hilarious! Anyway since there is only one abyss it might connect to every human realm above in roughly the same way. I’m just wondering if he goes back home eventually.
