(Grabs onto Key and shakes him) Listen here you pipsqueak! Wanting people who unjustly hurt you to get their comeuppance isn't mean, it's called being a human!! And yes, as painful as their consequences are, Surya and Casper are not innocent, Key! Who the heck blames a child for their mother's mistakes, and call you a monster for things he can't control!? (And mind you, we haven't seen the full picture yet, so accounts on what happened to your mother that day is still inconclusive) Who the heck asks children to hurt other children!? Who the heck tells a kid to go die like his dead mom!?
...Look kid, I understand that you don't want to hurt anyone. But not everyone out there will be as kind as you. Surya needs to learn that wallowing in self-pity has a price - his selfish actions caused a child under his care immense pain. Casper needs to learn that his actions will lead to consequences no matter what, and human emotions are not his plaything. In truth, the way that you were so hurted by their actions, the way you understand those two need to be taught a lesson, the way you never go out of your way to hurt them although you're justified to do so? That actions speaks of how kind you are, Key! Even at your darkest, weakest moments; never once did you wish to harm anyone! ...Cry as much as you need, but don't blame your heart for reclaiming the humanity others constantly strip away from you, OK?
"...Thank you. That...means a lot."
He feels a little better. The words mean a lot, even if his heart still feels fractured.
