Hey I am looking for a specific Dean/Cas fic that starts when Sam and Dean are kids. Cas ends up hurt and John finds him and takes him in. At first John is disturbed by Cas because he doesn't seem like a young child, Cas realizes this and hides his grace from himself essentially becoming a child. John raises him with Dean and Sam to be a hunter. Dean and Cas end up together and John finds out and kicks them out, or at least Cas out. Dean makes the deal same as canon and Cas rescues him again, but I don't remember when he gets his angel memories back.

I don't think its a timetravel fic but I could be wrong

Any help would be appreciated! Thank-you!!
