Shane leads the survivors until Rick's arrival, then becomes Rick's right-hand man. The reunion is not completely amicable; in the second season, Shane develops into an antagonistic character, becoming more aggressive and unpredictable, due to his growing obsession with Lori and subsequent jealousy of Rick. He also becomes willing to abandon or kill those he deems liabilities to the group and has no moral conscience for outsiders. This puts Shane at odds with Rick's moral leadership, as he believes that Rick is ill-equipped to lead and that he would be a better leader. His only true concern becomes for Lori and Carl, and not the group itself.
