Also did anyone else catch those parallels between Sam and Jack? Both of them have something bad in their blood. Sam has Demon blood running through his veins, Jack is literally the son of Satan. However despite that, both of them are extremely sweet cinnamon rolls and are genuinely good people.
And, as pissed as I still am at Dean for continuing to suggest that Jack can only be evil without even really, truly giving him a chance, they’ve both at one point asked Dean to kill them should they turn out evil. Jack just now with his “who am I? good or evil?” crisis, Sam after he was possessed by Meg and retraced the steps back in season two.
