"Supernatural": Friend and Foe Quiz

Answer: Yorkie

Dean tends to have serious issues with Yorkies. Not only did he run from one back in season 4's "Yellow Fever" episode but in the first episode of season 6, he nearly shot another Yorkie while feeling the effects of the Djinn poison.

Answer: Dodge Charger

Sam's choice of cars was one tip-off that something was seriously off with him, and his refusal to use the Impala when Dean offered it was another, but Dean couldn't have been happier when Sam's car got smashed.

Answer: False

In "Clap Your Hands If You Believe", the ninth episode of the season, after being captured and escaping from a group of fairies, Dean actually was able to see the little flying creature when it attacked him in his motel room and to escape it he trapped it in the microwave and...nuked it. Sam, on the other hand, couldn't see the bloody mess that was the microwave.

Answer: Scotland

Despite having a fear of flying, Dean went with Sam to Scotland (even though it didn't show that flight) as a favor to Bobby, who needed the boys to dig up the buried bones of Crowley so he'd have leverage on the new King of Hell to break the contract Bobby had made with him.

Answer: His soul was gone

In the beginning of episode 7, "Family Matters", Dean called on Castiel to finally tell him what was wrong with his brother. It was then that the Angel revealed that Sam's soul was gone and still in the Cage with Lucifer and Michael.

Answer: Bobby

Not wanting his soul returned for fear of having to deal with the emotions and memories of what he'd done while soulless, Sam called on Balthazar for a way to block his soul from being put back in if Dean was successful.

The Angel informed him he'd have to kill his father or the closest thing to it, and that was Bobby. Luckily Dean returned in time to prevent that from happening.

Answer: Castiel

Seeking to buy himself time and to distract Dean and Bobby, Castiel broke the fragile wall that Death had put up in Sam's mind to protect him from the time he was in the Cage.

Answer: Vampire

In episode 7, "Family Matters" Dean and Sam joined the Campbells on a hunt for the Alpha vampire. It was also this episode where they learned that Christian Campbell was under the control of a demon.

Answer: True

After Crowley had a demons kidnap Lisa and Ben, and then had a demon possess and nearly kill Lisa, Dean decided it was too dangerous to be around them and asked Castiel to take their memories of him.

Answer: Dean

In episode 16, "...And Then There Were None", Sam, Dean, and Bobby were joined by Rufus to look into some deaths that involve Eve. They came across Samuel and Gwen, and while being possessed by an evil wormlike thing, Dean shot Gwen.

Samuel was also killed in this episode...twice, since Sam killed him and then he was electrocuted while also possessed by the worm. Bobby too was possessed by it and killed Rufus.
