Gotham, Wayne manor, Friday night. This became a habit of yours, to come to watch a series with Cassandra, ordering pizza and a few other snacks and drinks, only so you two could watch a series, you are the one talking most of the times due to Cassandra being more quiet, but you don't mind, since it's obvious Cassandra enjoys your company.
"Thank you." she said out of nowhere smiling at you, holding a slice of Pizza, wearing her comfy pajamas. As you were turning on the TV, you turn around to look at her, wondering why she said thank you.
"For doing this with me." She said, and suddenly things made sense in your mind, maybe having you watching a silly 90's series with her was the most normal thing for Cassandra to do, that's why she was thanking you, for giving her a chance to be a normal girl for once.
