The feeling of being watched did not last long, and faded, as if it lost interest. Why wouldn't it? Based on all appearances, both Lex and the turtle were in the mortal realm. Because that completely made sense. It was a very common thing for mortals to teleport on an interstellar scale without suffering any harm. Why wouldn't they? It was not as if their physiques were so weak that the pressures of such travel would destroy them.
Sarcasm aside, mortals really could travel the universe as long as they used the golden keys of the Inn. Yet others could not know that.
Such an obvious loophole should have aroused greater suspicion from anyone scrutinizing them, yet since the turtle wished for his camouflage to be perfect, it was, and mere immortals could not see through it, or even conceive the idea that there was something amiss.
This was only the first step in the turtle's plan.
