Cassandra and you were both in the Batcave today, or rather you were both left to watch the house along with Alfred, and the rest of us either went on patrol or, like Tim, hung out somewhere on the computer for a very long time.

Out of boredom, you both decided to go to the Batcave gym, but instead of doing a typical workout, Cass decided to do a different, special workout. You changed your clothes before noticing Cassandra standing in the middle, clearly waiting for you, so without hesitation you approached her.

You stood there looking at her confused before without warning she grabbed both of your hands and pulled you closer almost pressing your body to hers but her face didn't become any less calm or stoic.

— "Dance with me."

She said it straight out, as if it wasn't a question. Well, it wasn't a question, you don't have any options. Cass could easily make you dance the pas de deux, but she knows you're inexperienced, so that she will involve you in a lighter dance.
