I saw you were having a bad night yesterday. I hope you are better. Here's a happy thought: It's the season finale. For once everything is going good for the boys. Cas is getting better, Dean's coming to terms with what happened, Sam's healthy. But Sam's been having headaches. Nothing a few painkillers can't fix. But one headache happens near the end of the episode. Then Sam looks at a doorway in the bunker and Mark Pellegrino is standing there. He says "Hey Sammy. Miss me?" Then it goes black.
