Kon turned to stare at him. It was hard enough to fight natural anger, but when it coursed through every fiber of his being it was even harder. It was nearly impossible for him to fight it but he was trying. Clark wasn't a threat. In the very back of his mind where Sanity still existed, he knew that. He didn't attack on sight, he struggled internally to maintain control. The Fortress was the one thing keeping him together, logically he knew that nobody could get there but them, not without assistance anyway. It could only be Clark talking to him, and he knew Clark would never hurt him unless there was no choice.
That calm outlook helped the younger Kryptonian, gave him something to focus on instead of the anger. Clark wasn't looking to attack and his movements weren't threatening. The red tint to his eyes began to fade a little the more Clark spoke, the more he tried to reach out to him. Kon finally registered his voice as a friend and the violent color darkened entirely after a few long tense minutes.
"Nobody else?" His voice was hurt and confused but it sounded more like him then he had all day. His senses were on high alert, the Fortress was even easier to hear others in. If Clark was tricking him he would know it in an instant, but he tried to give him the benefit of the doubt. Clark had never hurt him of his own free will before.
All it took was Clark's reassuring presence, blue eyes finally met with his. Worried and afraid, but blue.
