The fact that Clark actually needed help in walking to Annie's shelter, it said a lot about his condition. He found himself slipping into unconsciousness by the time he was almost there. He realized that he had taken the sun for granted.. but no more. He knew that in time, if things stayed as they are, then the planet could die.
Somehow, he found himself healed, and someone he didn't know was the cause. Well.. that was probably a bit of an exaggeration. He wasn't completely healed. He was at least awake. His arm wasn't numb anymore. And he could certainly still walk around. It was just that... he didn't feel as strong as he was before.. by human standards. He didn't recall ever having a headache before. Probably couldn't open up a jar of peanut butter without a bit of effort on his part.
Well, at least he was alive. He was grateful for that. When he heard Angel speak, he slowly held up a hand in reply. "Umm.. yeah. I'm okay. I'm fine now." Though he could be better, but he didn't say that out loud. Things were already stressful enough. He knew he'd be back in top shape once the sun had returned.
