Part of Clark wanted to turn around and rest right there. He felt that a lot had happened and the adrenalin was fading away leaving him weak. However, if he didn't push himself beyond his limits then he would end up stuck as a weakling forever. He could stand up to those slightly stronger than him right now, but he was all too far from one of the Mourne family members.
"Crim, I am going to be fighting alongside you and Devi. we need to make sure that we deal with everything as quickly as possible." Luckily, Clark still had the map and found it much easier to make things out in the dying light of the day.
As much as he wondered why he was able to have a better sense of sight in the dark, Clark chalked it up to his bond with Devi. Since he had trained his body before Devi had hatched and sent energy to him, it made sense that Clark would develop beyond the average for a tamer of his age.
