#Didn't Seteth mention smth about perpetuating their blood line in their s support too LOL

Do you think Seteth and Byleth might have a child of their own someday? Do you have any headcanons for that?

(Spoilers ahead i guess!)

Yeah! I think that eventually Seteth and Byleth will get to that point in their lives and have children of their own after all they have centuries ahead of them yet to come + Flayn having a baby sibling is cute af, no one can fight me here.

Also having Marcuil and Indech have another niece is a nice HC too, I made Flayn talk to them in their paralogues and after that I couldn’t stop thinking about it. 

As for any other specific headcanon… nothing comes to my mind right now. I can imagine Seteth being as alarmed as always and, even though he’s aware that he and Byleth have way too many duties to attend to, bringing the babe with him. In a way, I can also see Flayn making sure her baby sib gets all the attention they might need when their parents are just too busy to.
