Cal shook his head when she asked him if he knew what a Grey Jedi was. He couldn't help but wonder if it was something that he should have known about. Was it lost wisdom or something else? Maybe something forbidden? He'd have to find out more.
"I believe similarly... but it hasn't always worked out that way" he replied, some regret in his voice. However, he also knew times were changing. That the old Jedi Order was behind them and it was time to build something new. He had to do things differently to how he had been trained as a padawan. Even taking up arms and carrying a blaster had seemed strange at first, but he knew they needed whatever edge they could to stay ahead of the Empire. To stay safe.
"So you've used the dark side?" he asked. "And you use the light side? I guess that's what Grey is. A bit of both. Light and dark..." he trailed off. "Is that what..." he paused, cutting off his own question. It was far too personal. Asking her if that was what happened to her? Was she given redemption? Was she a Sith who turned to the light side? Or a Jedi who had been tempted by the dark side?
