Watching this episode, it was painful to watch one of our heros being tortued for information, killed, brought back to life, and killed again. Thankfully Daniel comes to visit him after he was ascended but is unable to do anything to help him, only to offer assension. It was a very good episode between the relationship of Daniel and Jack, and how it hurt Daniel that he couldnt do anything physical to save his friend, and Jack's frustration that despite DAniel being his friend he wasnt helping him escape.
It was a very powerful episode i thought. The scene in the end where Daniel says goodbye to Jack and tells him he'll be okay, Jack asks if he'll be okay and if he'd stay longer. The last scene was the best when Jack says thanks to Daniel as the camera pans out to an empty room.
