Firo elects to ignore her first point. His humanity and durability aren't topics he cares to discuss right now.

He listens through her list, nodding stolidly at the end. "Yeah. You would. Because it doesn't matter what you're made of."

He's not budging on that. Never.

"That's great. It really is. Just watch how you go on about 'bein' useful to other people.'"

If he were the type to think about his words, he would have considered that wording more. Helping others is one of the most important things--he's call someone a selfish fuck if they tried to wiggle out of it. That is, if the person being helped deserved it. As far as he's concerned, a lot of the people Rey would help don't deserve it anymore.
