Beth was a little girl at the time. She thought it was the coolest thing ever, like a tiny living doll. The way the Mangas think of Bree is more like she’s a pet. They just thought of it as giving their daughter a new pet. They impressed on her to keep Bree secret. Over the years, they slowly bonded together (stockholm syndrome, but at least Beth didn’t take advantage). She even did all she could to keep her brother from ever laying hands on Bree.
It’s starting to look like I might want to start writing out Bobby’s encounter with the trapped borrower. As for the field borrowers… stay tuned.
For Sam’s family… at least now that they’ve met Dean, they aren’t as wary of humans as they once were. They will be more open to meeting a person like Bobby. Whether it happens or not… only time will tell.
They discovered the people his size a year before he was cursed. His adopted sister, Bree, was in a motel room searching for supplies and she was caught by Chance. She was taken away and given to their daughter as a present. Details can be found in chapter four of Taken.
Walt would accept Sam just the same. He understands that Sam doesn’t belong at their size, no matter how long it’s been, and he also knows that Sam would never do anything to hurt them. He might get stiff on occasion, but he’d never turn Sam away.
Bree would be better with Sam than she is with Dean. She knows him, as well as she knows anyone, really.
