Manipulating the system
Lex sat in his office ruminating over the systems intentions. He had not lied when he told Ming Jie that he had to be careful about following the systems direction, for the system would endlessly push him towards its own goals, but Lex had experienced first had how getting in over his head had caused him problems.
Other than that, he also thought about the problem regarding his family. He was more than inclined to just ignore them, but just because he ignored them did not mean any problems they could cause would ignore him. Yet at the same time he was not in the mood to go face them, or investigate himself.
He also didn't want to use his resources at the Inn to investigate, because he did not know if the system had any relation to them. It was a headache all around.
