Giving the kid space was probably the best thing Clark could have done in that moment, had he approached any sooner chances were high that he wouldn't have been able to handle everything that was flying at him at once. He didn't understand why either, what had he done to deserve the universal backlash? It wasn't enough that he'd helped take down a horsemen was it? Or maybe it was that he had and the seal wasn't entirely thrilled with him. Kon paced through an empty ice hallway. The cool draft the cave gave off didn't even phase him, but it never did. He didn't feel temperature change, even if he flew to the sun he wouldn't have felt it. Even with his blood boiling he felt nothing aside from pure unbridled anger.
In giving him that space, Kon was able to calm down a little bit. But still couldn't hold himself together much longer. He wanted little more then to fly back to Kansas and beat Prime down the same way he had been. Make him eat asphalt and watch while he suffered and bled out. He wanted to repay him for everything Prime had stolen away from him when he took his life.
In the back of his mind Kon knew it was wrong, and that was why he left. He didn't want to turn into a murderer but he couldn't control his anger with that wannabe in the same state. Instead of dealing with things the way he had before, he left. He left and still there was a question in his mind of whether or not he'd done the right thing. He'd demanded Prime leave, made a few probably hate him or think of him as a monster. But what would they have done if the same guy who killed them showed up and came skipping into the complex like everything was history? It wasn't history, to Kon he still remembered every minute of that last battle. He remembered every ounce of gravel that dug into the back of his neck.
His senses were on overload when Clark came into the corner of his eyes, he had to fight every genetic instinct to not attack him on sight. Clark wasn't his enemy. He wasn't there to hurt him. Conner Kent knew that, but Experiment 13 was struggling. For the longest time he just stared, eyes narrowed and fixed dangerously on the older Kryptonian. Reading his every movement.
