It's clear Felix is starting to be shaken somehow. But..... how? Why? It doesn't seem as though he remembers any of the people or things Seteth is talking about. It isn't as though there's anything there to tug at his heartstrings. (Is there?) But if he can capitalize on that, keep him talking, maybe draw him back in..... It's not guaranteed to work, but maybe he can keep Felix from going somewhere he can't follow.

The voice in Felix's mind gains an edge of steel, stern and authoritative even if he doesn't raise his voice. "That's not for you to decide. What happens to my friends will always be my business; whatever your feelings on the matter, I am not turning my back on you."

He will care about you whether you like it or not, you little shit. Let people love you!111
