It would likely trouble her equally to know he was the one that created the collar she wore. She had no real reason to escape, nowhere to go, and she was raised with the belief that humans had a right to own mutants, for the good of the world, the good of humanity and the good of the mutants themselves. She didn't agree with the arena though, that.. that was a bit much. It was beyond her scope of training, though to be obedient was not, and thus it was accepted, even if it was disliked.
She is quiet, reserved, not terribly in touch with her emotions true, but were she extreme in those issues she would not have greeted him in return, nor dropped from her perch to join him, would she?
Those green eyes flick over the blueprints again, and though she could not build from them, she was smart enough to understand schematics and layout. "Mm, that depends on whether or not I may choose which room will be mine." She lifted a finger and tapped the blue color code insignia on her collar. A hint of humour in her tone, but polite, respectful all the same. One tiny finger points to the room that is the most structurally sound, and the one with the fewest acoustics issues judging by the blueprint, at least as far as the dormitories went.
