I'm not trusting them! I know you can't trust demons Sam... Believe me, I know! But, dammit... He said he could help us stop Castiel and Lilith. All he wants in return is for us to leave him alone. He said he don't want our souls, and he wants me as far away from Hell as possible.
If it means saving lives, Sam, I'm about ready to try everything. After what I saw... I'm not sure who we can trust, anymore, besides eachother.
