Oh, poor Harry. I recognized so many signs of illness. I love how you wrote Harry's dialog in such a simplistic way that it conveyed that flat affect of the depressed. I assume that red potion is real and was Snape's for himself as a painless way out. It breaks my heart to think of Sev caring for himself like that, that he would make a good-tasting potion that evokes happiness as you pass away. Harry seemed so broken (love that moment of clarity when he sees himself all drawn and scruffy in the mirror)that I'm glad he took comfort in the sense of purpose Kingsley gave him, and the love and comfort Severus did. I assume he got to the real Severus right at the end for always. Lovely.
