It was a post Rumbling world, several years after the event, in fact. And Reiner had taken on a more permanent ambassador position in Paradis due to him and you settling down with your now two year old child.

and he was a great father- better than you ever imagined. He was gentle, he was caring, and he was the sweetest thing to his little copy of you and him. And he was currently trying to wind them down when you came in, which made Reiner turn to look at you with surprise.

“Back already?”
