You and Sam never anticipated having a baby. Hell, you guys weren't even together. It was just some stupid, emotional, drunken hookup. And it led to the most important thing in your life. Your son.
Now, so much had been going on at the time that... Sam was barely around. Even after you had the baby, there was always some supernatural shitshow running his life. And then, jumping into the cage and being soulless for a while led to him being gone for another year.... he barely knew his son.
But now that everything was... well, for once, calm... you left your son with Sam. You needed to go out and boy some things... but you also wanted Sam to get to know his own son, which he had met maybe a handful of... four times?
The boy was now two.
The toddler was sitting on the floor, quiet for a toddler as he played with the toy car that had been in the bag of items you left for Sam.
He sat there... doing research... completely out of his depth as the young boy he barely knew was now under his care...
