The tests that Kellen had to go through made him exhausted. It was something he had noticed with the condition of his body right now. He didn't have as much energy as he normally did, and he had a feeling that was because his body was trying to win against the poison in his system.
What also didn't help was the fact that Taylor and Carlos would go outside and whisper to themselves after they got the results of a few tests, debate for a moment and then come in and declare that he needed to go through a few more tests.
It was exhausting, and felt very similar to the types of tests that he had done on the front lines when he had first woken up. He wasn't going to complain though. If he complained, that would make him an asshole. They were able to do these tests because he was awake, unlike everyone else.
He was just glad that he had sent Rhys away with he had.
