Strange looks back at Fleshy for a moment. They share a look (which is kind of creepy as Strange isn't blinking) before Strange decides that yeah. Peridot's right. She's right both at the 'you say mean things' bit and the 'it doesn't matter anyway' bit. Damn, Peridot's smart.

"You're right," he says, as he offers Peridot the frisbee. "We shouldn't care that we're mean or that we're not nice people. We're amazing anyway."

This is 100% the wrong lesson to take from this. Strange awkwardly starts unbuttoning the top two buttons of his shirt, just so he can get better access to one of his mirrors: a large portion on his right shoulder that looks like it would cover a gunshot wound and a bit of the skin around it.
