Dean watched the expression on her face as the wheels in her head tried to process the information he just said.
"I watched...like the first two episodes. To get some info on you but then I sort of figured I could just ask the source."
He smiled up at her a little. His own morbid curiosity is what turned him to watching his own show which in turn turned on the anger. More of the despair that he wasn't going to be able to save Charlie. And even more darkness that he would speak just as Cain has spoken to him the first go around. With condemning someone just because of their family rather than their own merit. It was heartbreaking in its own right and something he didn't want Liv to know.
But it only proved that he was right about being a monster. Perhaps, in his own mind, worse than Liv was. Or what she believed she was. "That Blaine guy's a dick though. Just throwing that out there."
