Afterward, he follows the serial killer to his home and is shocked by what he finds. Dexter also has some explaining to do when Rita finds out that he never gave up his apartment and still keeps some of his possessions there. Sgt. Batista plants a news item about the suspected Vacation Murderer that bears fruit. Having told her superiors of her relationship with Batista, the Deputy Chief delivers some bad news to Laguerta.
