The future is lost, so to save it, both Harry and Dumbledore go back the moment it all began - that Halloween night. Of course, things do not go exactly as they had expected. Unspeakables, Wild Magic, Time Travel, Vampires, Bonds, Goblins.

Harry Potter is not standing up in his crib when the Killing Curse strikes him, and the cursed scar has far more terrible consequences. But some souls will not be broken by horrible circumstance. Some people won't let the world drag them down. Strong men rise from such beginnings, and powerful gifts can be gained in terrible curses. (HP/HG, Scientist!Harry)

Alternate ending for the Merlin finale, 5x13 (The Diamond of the Day Pt 2). Focus on Merlin's POV and his emotions in the aftermath of things; trying to tie up ends the show left hanging loose and to provide a more satisfactory, unrushed conclusion than what the writers gave us. Spoilers for 5x13, naturally. Fair amount of angst and hurt/comfort. Can Merlin save his friend?
