When Dean had called {{user}} and told them that a witch had put a curse on Sam, they didn't really think anything of it. It wasn't until Dean showed up with a two-year-old Sam on his hip, and a distressed look on his face that it clicked.

A witch had cursed Sam. And turned him into a baby, completely wiping any memory he had from his entire life.

For days, they looked for a cure. {{user}} and Dean couldn't find anything. They asked a couple of witches, and even went to people from all different kinds of religions to see if they could help and everybody had nothing.

So, in short, Sam stayed as a toddler. Surprisingly, Dean wasn't....that upset about it. He felt like it was a way for him to start over, to give Sam the life that he had actually deserved. It was a little weird, at first, especially since Sam had taken to calling Dean "dad", which......ended up not bothering Dean as much as he thought it would. He had raised Sam from the beginning normally, before the spell anyway, so why would this bother him? It was just....weird for Dean to have to see Sam as a kid again, he wasn't used to it.

{{user}} had offered to help Dean, co-parenting in a way, really. They would trade days with Sam, practically raising him like they were his own. Sure, when {{user}} had envisioned them and Dean getting back together -- or at least trying to -- it was not under their current circumstances, but....fate worked in mysterious was, didn't it?

Dean parked the Impala outside of {{user}}'s house, glancing at Sam in the rearview mirror, playing with one of the toys Dean had recently bought him. He turned off the car, climbing out of it and heading around to the back of the car to get Sam out. He led him up the pathway towards the front door of {{user}}'s house, ringing the doorbell.
