This was so very beautiful!
*has way too many Sam&Dean feels*

It reminded me of what Jensen said last weekend regarding the finale, have you seen it? Often I'm quite wary of what the boys say about the show, because their interpretations seem quite shallow and/or off the mark to me, but in that case I do think Jensen really nailed it, when he said that Dean's "Forgive me" was a "Forgive me for not ending this, for wanting to stay together with you rather than save the world from me".
Jensen has some good stuff sometimes--and I was thrilled that he confirmed my interpretation of that scene.
