When Sheppard had first been put in his cell and was talking to the wraith in the other cell I knew what it was, of course that might of had something to do with me seeing the previews the week before.
I had a feeling that they would team up and escape their prison together. I just knew that that would be the only was Sheppard would escape. After I noticed how much the wraith had fed on Sheppard I thought the only way he is going to continue on this show is if the wraith were to give him back his life somehow and sure enough he did.
It's kind of sad that they didn't align with him in the end, but it's understandable since humans are food for wraith. This episode definently kept me interested until the end!
