I get that Dean is supposed to see what happens when he says, 'no' and what happens if he lets Sam go but it seemed pointless to me. I thought Jared was good as L-fer though I wish L-fer was more ruthless with his speech. And having two Deans for the ep was weird...and future! Dean's voice...omg. It was very 'Batman-like' ....though I guess he WAS a viligante.
i'll post a proper review soon!
