Kyle's weird behavior was accepted by everyone after they were allowed to beat him to a pulp. Nobody really hit him hard, and Jaden didn't even think about hitting him but it was obvious that the girls were frustrated that he had been silent about a few things.
First of all, there was the fact that a powerful beast was likely to hibernate below the Cave of the Lost Arc. Second, that beast was the Black Dragon, which Kyle figured owing to the paths of development that were in resonance with the dragon scales in his possession.
Kyle trusted the Black Dragon, who was an Old Soul and he believed that it would never ever injure him. This was weird, especially because another Old Soul was likely to be on his way to find the Lost Arc, the key, and the key-wielder.
Kyle was the individual, who could wield the key, so he was the key-wielder. He was also in possession of the key, and was on his way to the Lost Arc.
