This turned out so wonderfully! I enjoyed reading it the first couple of times around, and this time's no different. I still love the scene with them swinging in the playground so, so much. The subtle yearning that Snape has for something he knows he can never quite possess because "Hannah" is just not the real Lily, yet taking what he can get by swinging while holding hands with Harry... that scene gets me every time.
Of course, Snape the bastard is thoroughly enjoyable as well ;)
