"There's a certain level of prejudice against my people too, on the world I lived before coming here," he says slowly. "We believe in treating humans with respect and compassion, since we were the ones who stumbled onto their world uninvited...But it's not always easy. Some people insist that we're only pretending to be sapient, as little sense as that makes. Some people are angry at us for bringing our war to their planet. Or people just seem to hate the idea of thinking robots altogether...Before I wound up here, somebody accused me of trying to turn his daughter into a robot. I was fitting her for a prosthetic so she wouldn't lose her ability to walk after a spinal injury."

But he's not bitter about that, despite everything that happened afterwards. He's just...extremely sad. It was really, tragically sad.
