Dean Winchester : I'm sorry about what happened last time we met, I'm sorry for a lot of things, I'm not that person anymore

Dean Winchester : My kind?
Dean Winchester : [Cole throws holy water in his face] I'm not a demon anymore
Cole Trenton : Were you a demon when you murdered my father?
Dean Winchester : No
Cole Trenton : Then you're still a monster
