Kon wasn't phased by Robin's appearance. He could hear him coming long before he even reached the door, but that wasn't something he often told people. That sort of thing could be unnerving to some, and he really didn't want to lose friends because of it. He could hear their heart beats as Clark could, he could hear them from miles away. Some people would simply not have wanted to know. Krypto was near by, his white lab with the iconic red collar and house of El symbol dangling from it. The dog hesitated at Robin, unaware who the man was, he stared him down with an intensity that many dogs might not have had. Then went about his business as if he approved and wriggled his way back inside the complex. He could leave, Kon wouldn't be alone.
He was rarely alone, but it sometimes felt like even in a crowded room he was. However, today was not that day. Today in that building he felt more crowded than he ever had. He could hear people talking non stop, voices whispering about Death and the Horsemen. Fear over the apocalypse growing closer, and he couldn't block it out. Clark had been working with him since the day the sound shattered around him, but he still had some issues. Anger and control to name a few. "Couldn't stay in there. I can hear them all. It doesn't stop." He usually had head phones for that, but on days when he felt weaker they didn't help.
His eyes were naturally a blue color, almost piercingly so. Everything about him matched Clark, just smaller. "They're all talking all at once. I'm the one who broke the finger off of Pestilence and took his ring. I still can't unsee that face."
