It just seems stupid that Demons are busy trying to make babies when they don’t need to.
But then, Rupert would not have existed. So maybe there is a positive side to this sex thing.
There is also the problem of Tom’s children being half demons. That would be especially difficult to those children as exemplified by Rupert. Rupert already expressed his desire to end his life. Well that would not be a problem, I think, if Tom behave like Antefalken, not caring about his offsprings and all. His children could kill themselves for all he cares.
