Lisa & Adam
The name sounded vaguely familiar and it took him a moment to place it. "Snart," Adam repeated. "There was a guy here with that name. He was friendly with my housemate." Well, he may have been more than friendly with Sam, but Adam didn't really want to know about that.
"Met him in passing," he said. He assumed this was a sibling though with the way this place was, it could be a parent or grandchild or something else crazy like that.
