@xdbx as much as I don't trust his ass either, I'm thinking that, assuming he's that much more powerful, he WILL let her off the hook "accidentally" (tee hee oopsie or something childish like "she got away because some deus ex machina happened, can't be helped") and leak the right information to her family "accidentally" under multiple layers of encryption.
tldr: he MIGHT actually truly be sorry for trying to pull her into his situation, but due to his station, he HAS to do this for appearances' sake. Or Seraph might end up as a backup measure, as an exile who knows hidden truths about the royals and the rules of the world.
If that makes any sense.
