This was one of the most interesting reads I've had in awhile. The combination of memory loss and Draught of Living Death was seamless and the effects it had on Severus' personality were well thought out and shown. The kids were very much kids in this, too; you got them down pat. And Harry's line at the end fairly made me swoon:
Fuck me. Make it angry if you like, but make it good. What quiet desperation and need! Well done, anon!
