Dean likes staying at Pastor Jim's. It's a real house with nice beds for him and Sammy. It feels safe there. Until Dad leaves.
There are cars and lots of places to run around and play at Uncle Bobby's and Dean likes staying there even better. Except when Dad and Uncle Bobby fight.
His favorite places are the motel rooms they stop at each night, staying only when there's a hunt. They're usually small and noisy and sometimes they smell funny. When the word home comes into Dean's mind he squashes it down. Home is Dad and Sammy; nothing else.
