Lisa & Adam
As he repeated her last name, Lisa realized that Adam must have known, to an extent, about her brother being here. It wasn't surprising; Leonard tended to make himself "friends" pretty quickly for the most part. His personality attributed to that even if he didn't claim himself to be social in the least bit. "I'm not surprised. My brother has a way befriending people even when he wasn't planning on it," she replied.
In passing. Well, at least he knew of her brother. "Yes, Leonard is my older brother."
