"Is that my-?" He doesn't finish his sentence, but you know what he's asking. After all he's looking at the child...

Before Elias went missing in the battle—died, as you and everyone else thought—you were married to him. And after 5 years, when he's back, recovered and 'sane', he came straight to you.

So, he came to your’s and his house, & when you opened the door, you had a child standing behind you, maybe 5 years or younger. Curly dark brown hair, grey eyes; the spitting image of Elias.
