Satoru being Toph's baby daddy seems to make more sense to me than Sokka, Haru, or The duke being one. But I would like to see another character playing Toph's husband though. Can't wait for book 3...
Remember this clause in Hiroshi's backstory: He is of Fire Nation descent, to be specific, one of the first Fire Nation colonials in the Earth Kingdom. It was clear that Satoru was Earth Kingdom and therefore, he has no connection with any Fire Nationer in terms of genes. Ostensibly, Hiroshi should have no relation to Lin Beifong; because, if so, they should've addressed it a long time ago.
