Me? I know I'm a freak. And sooner or later, everybody's gonna leave me.
Dean: I really wish things could be different, you know, I wish you could just be Joe College.
Sam: Nah, that's okay. You know, truth is, even at Stanford, deep down, I never really fit in.
Dean: Well, that's 'cause you're a freak.
Sam: Yeah, thanks.
Dean: Well I'm a freak, too. I'm right there with you, all the way.

For this episode = 2 humans and 1 shapeshifter.For the series so far = At least 109 humans; 4 ghosts; 1 shapeshifter; and 1 wendigo.
Absurdly Spacious Sewer: Sam and Dean pursue their quarry into a sewer large enough for them to stand upright, occasionally walk abreast, and a spacious lair for the shapeshifter. Large rusty pipes and large amounts of moisture complete the expected look of an ancient underground despite the episode being set in St. Louis, MO.
Bluff the Impostor: Sam and Dean are hunting a shapeshifter. They split up, and when they go back to the car Sam asks Dean something about a mission done by their father. Dean gives the right answer, proving that he is himself. Except that the shapeshifter can access the thoughts of the person it is mimicking and actually had copied Dean. Sam still sees through it when "Dean" uses the arm the real Dean had injured.
Body Horror: A shapeshifter is killing people, and Dean theorizes that shifting involves shedding his previous skin. Late in the episode, we see him shift. Dean was right.
Busman's Holiday: While it's not really "holiday", Sam and especially Dean didn't expect that helping one of Sam's friends would end up with hunting a monster.
Clear My Name: What Sam and Dean are trying to do for Zach. They succeed when all the shapeshifter's crimes are pinned on Dean. Police figure that Dean tampered with the video recording of Zach at the crime scene.
Cold-Blooded Torture: The shapeshifter ties its victim up, tortures her with a knife, and leaves her either to die of her injuries or be rescued by a third party.
Criminal Doppelgänger: A shapeshifter impersonates people close to the victims while committing his crimes so that they'll take the fall instead of him.
Deggans Rule: Failed. Although one of the minor roles, Alex, is played by an Asian actor.
Evil-Detecting Dog: One of the first clue that something supernatural might be involved is that the dog next door has become vicious since the attack.
Faking the Dead: The dead shapeshifter is indistinguishable from the real Dean.
Fan Disservice: Dean seducing Becky? Fine. A shapeshifter pretending to be Dean seducing Becky as a prelude to brutalizing and murdering her, not so much. Followed up by the shapeshifter removing its skin, complete with werewolf-esque writhing and screaming.
Wrongly Accused: The secondary victims of the Criminal Doppelgänger. This episode also start an important subplot of the show, with the brothers being hunted down by the police who believe them to be some sort of homicidal maniac family.
