Astrid glanced up as someone entered; upon seeing who it was, she merely nodded. While she had little idea who Raven really was, she did at least recognize her.
She couldn't imagine the other girl was at all interested in what they were doing, so she was content enough to remain silent and simply continue on the game she was engaged in.
Felicity was not quite so aware of the situation, such as it was. She offered Raven a smile and gestured to the cards. "Would you care to join us? I'm certain we can make a three player game out of this."
She was clever enough, after all. It wouldn't be difficult to devise a simple game the three of them could play.
