[Claire downs her drink, indicates for Castiel to do the same, and so he does, the alcohol burning its way to his stomach. He's sure he'll come to regret drinking like this, given that his angelic abilities are altered here.

It took me a long time to be able to name what I feel for Dean. I doubted and questioned everything; I didn't understand why Dean means more to me than others, what about that difference really distinguished between familial love and romantic.

But one day, I just knew. The truth of my feelings hit me, like a pie to the face, as Dean might say. I felt as though I were seeing the sun for the first time. It was... terrifying, admittedly. But also liberating.
