Soldat hesitates for a long moment. They haven't told Otoha that much about their own past-- their own status as not-a-person(-anymore). Not being a person means not having responsibility for where you were pointed when your trigger is pulled. Even if they do feel... something about it. Definitely when it comes to being pointed at Steve.

They're not sure if it's appropriate to bring it up, now. "I don't know. Maybe. And you killed yours, so at least. They can't point you at anything or anyone again."
