Also, have to add that, iirc a Ronin is masterless, but in the sense that they don't serve any master or lord. Traditionally, ronins were samurai (something akin to a knight) who had lost the lord they pledged to, often because these were killed in their inner wars, some other times, because they fell and lost their lord's favour. It depends on how one takes Jason's loyalty and ties, I guess.
