Teacher's gonna show you, how to get an A
1) I thought Ruby told Sam that the demon blood-drinking was a Dumbo feather? That Sam had the power in him all along. Why does it really work? Why does he crave it? I'm sure this was talked about in 5.01-5.03. (And has he always been able to sense demons inside of people or was it just that he deduced that suitcase!guy was one with his Sam!smarts?)
2) Why can't anyone be in the Panic Room with Sam when he's detoxing? Couldn't someone sit by his bedside and, I don't know, put a wet washcloth on his forehead? Why do people have to stand vigil outside the door?
Can I tell you? I think I know a bit how Dean feels, because THIS SHOW OWNS MY SOUL. IT'S NO LONGER IN MY POSSESSION. &hearts_♥
Oh boys.
