Kitty nodded and pushed her hand under the pillow to raise the level of her head a bit. "On the one hand, that's obvious, right? But, for example, Yana and her brother Piotr are friends from home. They're not from the same version of home as I am, though." She chewed at her bottom lip briefly. "As far as we know, there can't be more than one of each person here, but...like Sam Winchester's brother, Dean. He was here once and was from earlier in the timeline than Sam. Then he disappeared. When he came back, he didn't remember this place and he was a lot older than the other version."
