"We don't. Can't tell you much on how we got him, just that I've had him under my wing for a while. Speaking of-" Cualli realizes that right now she's sitting next to a robot learning from her, who just saw her punch a guy without any provocation.
Cualli turns to Elu and places a hand on him. "First off, you did good back there. If you hadn't stepped in, Arkhip and I might not be around anymore." She's lowered her voice and takes on a sincere tone. "But I need you to keep in mind that violence isn't always the best answer, okay? It's okay to fight if me, Arkhip, or whoever is in danger-- like earlier. But it's a last resort option, especially given your position." She squeezes Elu's arm. "The last thing we need are worries over you rebelling against humans or whatever."
"Punching people normally isn't okay. I hit that guy because he was a threat, and that's okay- that's called self defense. You can fight back if it's in defense; that's why it's okay that you punched the person who stabbed Arkhip. But you are not allowed to hit or hurt anyone unless it's in self defense, done to protect someone like me, or if it's a direct order from me or my superiors, okay?"
