|“||Who cares? You’re not denying it. Everyone knows you’ve got a history with this manipulative shit--who’s to say you wouldn’t take a couple cans of food and lie about it like it was nothing? What makes you better than me, Lucy? You knew--you fucking knew--Cole’s girlfriend just died. He probably needed someone to confide in, to take his mind off of her--and then he meets you. And you willingly twist his fucking mind for your own gain, and all the evidence points to me?||”|
— Dean, to Lucy.
