Because the end failed Dean so much for me. I know that everyone think that it was everything in Sam's mind, but I still have the bad feeling it wasn't and it was real. If it was so, they would have deprived Dean of his free will, of part of his life...so I loved the episode until the last scene.

I know it's not like that, I know canon says it was unreal...but still...

Lazarus Rising is one of the best episodes of SPN.

Missed you.
