Your words make less and less sense. First you say my brother was summoned to your world, and then you say it's not really him, but something made of some--some incomprehensible sorcery that somehow acts like him. Can you possibly explain if my brother is alive or dead and how he came to be in your--possession, or care, or whatever you deem fit to call it?

[The idea of Sigurd agreeing to help save another world is the most believable thing about this. He--or--whatever this Emblem version of him is--probably didn't even ask any questions before agreeing.]

As for healing and manners, I use both when needed. You should consider lessons. I offer them regularly at the clinic.
