Kate and Open!
Kate heard about this video game portal thing and couldn't wait to go check it out. She left Lucky at home, gathered her gear, and headed for it. In retrospect, she probably should have told people where she was going and what she was up to, but sometimes when the mood struck her, Kate leaped before she... looked.
Video games weren't Kate's top priority, either. She'd played a bunch of them with her friends on her team, but the others were more into that kind of thing than she was. Still, she could hold her own with a controller. She thought this would be fun.
