"Ah... I guess you haven't followed the news that much..? Not that I blame you, I only today glanced at the interviews today so I could try to recognise the other knights."

Seth did say they don't have to answer, but Zafika has nothing to hide, and it would come up either way at some point. "But, well, I'm that knight who was rumoured to be in prison before this. And it's not even a rumour so..." They kind of just leave the sentence hanging with a shrug of their shoulders, and manage to eat a little bit of food while they let Seth take in the news that he was talking with a criminal. And an assassin to boot, but if their name hadn't said anything to him, he probably wouldn't realise from this additional information.
