I have such a thing for adaptation!fic, and I'm amazed both at how well you pulled this off, and that it's never been done before, because this is a perfect Snarry story! The way you incorporated first Arthur and then Harry, the way the camellias signal Snape's dangerous loss of body heat, their growing acceptance of one another - all terrific. I really enjoyed that Harry just accepted the way Snape looked - no disgust or reaction outside of his first startled one, but just that equanimity that's so much a part of him. Nicely done indeed!!
Coil_kitten - I keep having to stop myself from saying something annoyingly siblingesque. I really loved the picture of Snape in the mirror - the attention to the details of his face - the ridges above his eyes, the startled look - they really make the picture. Nice work, kiddo.
