Lex spent a little more time talking to little Pel to familiarize himself with the ring, and establish a deeper bond. The more he talked to him, the more he realized that Pel wasn't really capable of complicated thoughts at the moment. Although he had access to a number of the dragon's memories, his inability to form complex thoughts was most likely what protected him from being influenced by the dragon's past.
For now, his entire world was simple. Since he liked, and somewhat feared, Lex he would try his best to flatter him. At the same time, Pel would do his best to absorb materials to strengthen himself. But he was not greedy for materials, and he would not get upset when he was deprived of them either, as was evident from the fact that Lex did not let Pel have his skin.
