Arwen was a bit surprised. He trusted her because Jack did? Well she could understand that. Not saying that she wasn't trustworthy, but she didnt expect that so soon. She did giggle with the way he talked about avoiding hospitals. "Understandable. I haven't gone to a hospital ever since I can remember. I don't know why but I just do. Probably it feels like there have been more deaths than lives being saved. Just a guess. But yes. arcades are very fun. So many different games to try your luck, get competitive, or just for fun. Jack and I often like to play Skiball, dance dance revolution, and some of the racing games. Some shooting games are fun if you are in the mood but that's if we want to." She explained, not knowing if the Doctor had seen the immortal dance before.
