In the season 1 finale, he is promoted to head of the FBI's New York branch after Mayfair's disappearance. This is the goal of Stage One of the conspiracy behind Jane's tattoos: The tattoo investigations eliminated less ethical potential candidates; Weller also learns that Jane is not Taylor Shaw and that the real Taylor has been dead for years.
