Yes as an obviously new demon Tom seems to have managed to father a miniature version of himself roughly ten years of age. He was clearly working quite fast. He is likely related to Rupert somehow, but I don’t know how. Their has to be a powerful connection however as demons don’t normally look so much alike. They are balors and they can potentially rule over all lesser demons.
The whole fourth order half-demon will freak the others out and will once more cause others to grossly overestimate Tom’s abilities. He will do something unusual, amazing, and unique to escape the situation and with his acting skill appear to have done it on genuine talent as opposed to the luck and improvisation that we all know he employs.
