For a while, Clark didn't notice Loki at all. With his attention so focused on everywhere but where he was currently sitting, he had left himself in a position that guaranteed a full on blind spot to anyone who might have approached him. Clark remained still, the reassuring sounds of Kon's slow breathing keeping him grounded until the sound of an accident someplace along the outer edges of the city - well, no, almost, it had been narrowly avoided (the driver was shouting in frustration at someone else on the road) - forced him to open his eyes. It was in that moment that Clark realized he was no longer alone, immediately noting the sudden presence that had taken up space somewhere along his right.
The face was vaguely familiar. Clark wasn't personally well acquainted with the man, but he recognized him from back when things had gotten out of hand with the last Horseman that had come riding through the city, looking to give them all his own personal, messed up version of Hell. He was the one who had taken Kon down. He was the one who had helped, who had volunteered to do what was necessary should either of them loose control of themselves like that again.
Loki. That was his name.
"Is something wrong?" Clark immediately asked, observing the look of brief uncertainty that had overtaken the other man. Maybe there was something happening back at the complex? He had been so focused on Kon alone, that he hadn't heard anything else. No signs of trouble. Nothing he had any right to listen in on, so he simply hadn't.
But if Loki had come along, something had to be wrong, right? Unless the two of them stumbling upon one another like this had been all about chance, in which case...well, this would be interesting?
