"Because you view us as friends." These words were spoken hesitantly. Taking what Kuroro had said to him in previous conversations and applying it into the conversation of now. Understanding of what the word meant was still difficult -- what was a friend? Why did Kazuki want to make friends?

"This slow healing ... it is very ineffective manner in dealing with injuries." His body's physical attributes to heal itself faster than normal humans only shaved a little bit of time in actual mending. It also left him feeling 'weak.'

A slight shake of the head -- not at all insulted (but then, he rarely ever was when it came to critique about himself) since at the very least he was able to ensure that Tassadar was safe. "I am not used to fighting as purely a weapon. The limitations in what my weaponized form were made clear to me." This sort of thing should have most likely been tested properly before he had gone with Tassadar. He had gone to the training session so that he could learn information, but became sidetracked when Prussia wished to speak on himself and teach him how to laugh. It still sounded like a strange word 'kesese' more than a laugh to the clone.
