Changes

After learning that they need an [[Alpha]]'s blood for the [[Leviathan]]-killing weapon, [[Sam]] and [[Dean]] learn from [[Crowley]] that the Alpha Vampire escaped before [[Castiel]] could kill all of the [[monsters]] in Crowley's prison. Crowley gives them the Alpha's location, but when they get there, they discover that the Alpha fled to a hideaway after some of his [[vampires]] were killed. With the help of the Alpha's "special girl" [[Emily (There Will Be Blood)|Emily]], they locate the hideaway. However, Emily, once left alone, calls the Alpha and warns him and he captures Sam and Dean when they arrive. They explain that they're there for his blood and ask for him to willingly give it to them, telling him about the leviathan food additive. They realize that the Alpha has made a deal with [[Dick Roman]], but point out that Dick betrayed him and has made the additive fatal to vampires. Upon hearing that [[Edgar]] has arrived, and wanting to hear his side of the story, the Alpha has Sam and Dean locked up and meets with the Leviathan. They discuss Sam and Dean's presence and the Leviathan food additive. Edgar admits that it is poisonous to vampires and tells the Alpha that he needs all of his blood. The Alpha and Edgar fight, but despite the Alpha using borax against [[Edgar]], he is overpowered by him and nearly killed before Sam and Dean break free and storm in, decapitating Edgar. Owing them his life and knowing they have a common enemy, the Alpha willingly gives them a glass of his blood and when its insisted upon, the kidnapped child Allan he has. They warn him to not keep Edgar's head too close to his body for too long and leave, but not before the Alpha taunts them about wanting to kill him and tells the Winchesters "See you next season," which they are looking forward to.

===[[12.14 The Raid]]===

After the British [[Men of Letters]] begin hunting all [[vampires]] in America, the Alpha Vampire leads an attack on their base with the help of rogue [[hunter]] named [[Pierce Moncrieff]]. The Alpha Vampire ends up in a standoff with [[Sam]] who threatens him with [[the Colt]], offering the Alpha Vampire the British Men of Letters if he will leave Sam, Dean and [[Mary Winchester|their mother]] alone to return to the way things used to be. As Sam negotiates with the Alpha Vampire, he is attacked by [[Mick Davies]] while the Alpha Vampire is attacked by Mary. Afterwards, Sam reveals that it was a diversion so Sam could get and load a bullet for the Colt. Impressed, the Alpha Vampire calls Sam a "clever, clever boy." Sam then shoots the Alpha Vampire through the head with the Colt, causing him to laugh briefly before falling, dead.
