Good answers, and I'm happy to keep hearing more if anyone has anything.
If it helps, he would be a bondsman then new warrior in Clan Ghost Bear, in the 3040s. But as a character being portrayed, it's now in the 3050s and he's been a warrior in his new Clan for a while. He's a Star Captain and Chief Engineer aboard a warship, effectively the third in command. He's proven his worth and value many times. He's cultivated a lot of engineering expertise his Clan appreciates. He speaks some Japanese and so he has also been useful as a translator in interactions with the Combine and former Combine citizens now living in the Ghost Bear OZ. Some of the Combine's rituals also make more sense to him than they do to some others, so he's been useful as an advisor/mediator/translator in some situations. He's probably at the apex of his career. The Clan is happy to keep him where he is, and others with names like Jorgensson and Tseng are being promoted over and above him for the obvious reasons.
This is still a work in progress. The vision I have had in my head, is he's comfortable in his new Clan, but he still carries some baggage, knowing his genetic legacy will not be used and that he's practically exiled from his Bloodname House in every meaningful way. He's reaping the benefits of keeping his career going longer, and being a member of the Ghost Bear Clan Council, but that's about the only Bloodname "perks" he is receiving.
It's put him in a weird, unique place as a Clan warrior. He's gotten kind of philosophical about it. Meaning of life without genetic offspring. How to live and thrive without the support offered by a Bloodname House. It has given him a unique perspective on some things. So, he's regarded as somewhat odd. Warriors he serves with want to compare him to a Nova Cat mystic or Cloud Cobra cloister member but he's neither of those things.
I'm still working on WHY he chose not to commit Seppuku all those years ago. Like that was his first instinct, he was prepared to go through with it, but someone, perhaps his bondholder, tries and tries to convince him not to, and eventually he decides not to go through with it. I'm still trying to figure out what it was that got through to him. I want it to be something very good, and surprising and not what people might expect.
You all have given me some good thoughts on that front.
