Intriguing-in some ways I have questions (just how Harry seemed to be able to change the memories for one) but I don't mind them left unanswered. Harry's desperation to tell both his mum and Severus, the portrait of the two of them as living breathing children (well, teens), getting along, playing pretend. Gripping fic from the first words. I'll be thinking of this for some time I think. Well done.
