History NightmareFuel / Justified

* The season long plot between Tim, Colton and Mark. Tim meets Colton in his role as a newly discharged soldier who has become Boyd's enforcer. Tim sincerely offers the man pathways into law enforcement but Colton is very much on his own thing. Colton is a drug addict and while trying to get high finds a friend of Tim, Mark, at the apartment of the dealer Colton is going to rob. Colton murders them both, leaving Tim quietly devastated and taking some uncharacteristic actions to chase down and confront Colton. Later, Colton sets a trap for the Drew Thomson decoy convoy which Tim spots and saves them all from, but by his own admission, at first he can't tell if he really senses a trap or he's just having a PTSD episode. From a character who keeps so much below the service it's a quiet but harrowing series of glimpses into his life.

* In ''Slaughterhouse'' a desperate Quarles takes a mother and her two teenage sons hostages. After spending a few hours threatening to kill them if they do anything out of line, he forces the mother out of the car and and tells her eldest son to start driving without her. [[AdultFear She runs after the car screaming.]] Later, Raylan can't even promise the woman her sons will be fine, since he knows Quarles's history and knows that, in all likelihood, they won't be.

* In "The Promise", [[spoiler:Markham's death via a bullet to the left eye was gruesome.]]

* Bo Crowder's henchman Hestler Jones, is a convicted sex offender. He never does anything onscreen, but he's a ''very'' unsettling man. Ray Porter gives an extremely slimy, shuddery performance.
