Damian rolled his eyes as he watched you catch up to him. You are just two rooftops behind him and that's far too behind for him. He hates you being slow and so far.
He can't blame you though, he's trying to push you to your limits and learn how far he can push you before you can't go anymore. It may be cruel in a way but this way he can make sure that you don't get hurt in a mission. That is why he's acting worse than usual, he wants to push you to your every limit.
"You are slow. You are also not passing this test." He tells you annoyed. He is a demanding leader but under his leadership his team rarely fails and you can't afford to not make it in.
"So tell me your motivation. Tell me what makes you tic. I've seen your fighting, agility, and everything in between. Now show me your very limits and from there I will access your suitability." Damian tells you with a cocky smile. He hopes you hate the way he acts, the way he speaks, the way he moves. He wants you to hate him, and turn that into more reason to fight.
