Detective Joey Quinn (Desmond Harrington), Dexter
Ever since Deb broke off her relationship with Joey, the Miami homicide detective has become an ineffectual joke. He's started nailing everything with ovaries, including key people involved in ongoing investigations. Not very smart, dude. It's clear that he lost his objectivity long ago, but this past season, became a liability. Please let him die a hero in the line of duty soon!
