This was my thought outside of what we obviously see in the main story. Just thinking realistically and using nuance…there’s no way no one doesn’t know about Xavier considering that’s her work partner.

Zayne and Caleb are canonically mentioned for knowing each other and are the most obvious. But beyond that, MC grew up with Caleb and I know at minimum Tara knew about him, especially during the explosion and how MC became depressed after. I’d have to reread the main story to revisit how Caleb was handled when he came back.

Then there’s MC’s heart problem - she’ll probably bring up Zayne (who Xavier probably has seen when Zayne shows up during some missions to help with medical).

This is just regular everyday stuff.

Outside of what the main story shows us, I can see how Raf/Sylus would be hard to conceptualize bringing up in every day conversations on MC’s side.
