Though he was scared, Ark tried his best to calm down. He didn't want to appear weak, and he didn't want others to worry about him, especially not the little cub. Others worrying about you can be a burden for them, and Ark didn't want to become a burden in any way, shape or form. He just wanted to be a dependable figure in this small cub's life, not some weird homicidal monster. The scene around him was not something anyone sane would normally be capable of doing, at least not under the right circumstances, and Ark was barely even conscious while he did it.
