It...probably depends a lot on context and what more is revealed about the nature of the knight role / why only Sterling knights can individually contract with Personae / what the reason was for the opportunity to be offered / etc. Mithos does have a suspicion ICly that a knight who is not perma-allied with any one Persona will have a lot more general leverage in big picture terms than one who is, so that'd have bearing on his decision too.

Something Lloyd would like to ask Firebird about if she hung around long enough to have a good conversation.
