God damn it. -1. THIS IS A TERRIBLE IDEA FOR SO MANY REASONS. How about this for a trust exercise: if we come back and he HASN'T killed our mother, killed our bodyguard, ruined our name, had us banished, and stolen all our money, trading partners, and business assets, THEN we can maybe start to trust him. Jesus Christ... stepping stones, man.
I just gave reasons as to why I am fairly sure he wont act out against us, but I can give more. All else aside, he is a displaced person, and a guest of the Kingdom of Analysse. We are a prince, and possibly a future king, of said kingdom. He isn't going to start offing nobles, especially nobles who have offered to help him win his home back. Doing so would bring terrible backlash against not only him, but his entire race, and he does not strike me as stupid enough to risk that.
Perhaps he might try to rip off us much, much, much, later, but for now he needs us far more than we need him. There are several other lands to conqueror, and even many non-military ways to build our own power and reputation. Foreign Princes kind enough to be one's business partner, and risk taking up one's cause, are far harder to come by.
He might have the money, intelligence, and ambition to be dangerous, but for now, and for the foreseeable future, we are his meal ticket.
That said, I could be dead wrong. Its been awhile. I'll go back and re-read our interactions with Sekhom.
