While flying, improving his necklace, and harvesting more resources, Lex also began to address one of his most important concerns. He had no idea how long the barrier around his actual body would hold. Heck, for all he knew, it might have already been broken!
If, previously, he had some faint connection or understanding of what was happening around his body, now he could not sense it at all! He had a feeling that his stalker had put up some isolation barriers to make them harder to find - an understandable series of actions considering that Lex was supposed to be under the Innkeeper's protection.
What he did not know was that the reason for more isolation formations was not the Innkeeper, but the fact that his body kept getting feedback from Jack's and his own actions.
Previously, there was nothing he could do about it. Even if the barrier was broken, Lex could not do anything about it simply because he had no confidence in facing him.
