I was thinking of a plot bunny where Harry casts his memories backwards, and thought, who could he send his memories back into (other than himself). Here I thought would be a great use of two Longbottom bodies that are accessible in the future, and are known to be unused after a certain point in the past.

Surely someone has already done this fic? Perhaps he messes up and winds up in Alice's body? Does anyone know of something along these lines?

 

There's a thread for plot bunnies that you might like here. If there is a story like this, I'd be a tad interested to see it; I've honestly never seen anything like that, and I'm kind of curious as to what fics you've read that made this seem like an idea that would be done to death.
