Gee, after five seasons no one has bothered questioning the sheer number of dangerous killers that seem inevitably tied to Dexter? Not only did Deb eventually uncover Dexter's connection to Brian Moser, but Dexter himself was also observed sharing very heated ties to Lila West, Miguel Prado, and supposed Bay Harbor Butcher James Doakes.
Throw in mysteriously tense visits from Arthur Mitchell at work (the Trinity killings stopping shortly thereafter) and Dexter's relationship with Jordan Chase and it's a little absurd that no one once noticed a little too much excitement in Mr. Morgan's life.
