I know it's been ages since this was first posted, but I wanted to tell you that this is my absolute favorite time travel fic--and I've read quite a few. I loved how we were so worried that Harry was messing up the future by helping Severus and it took five years to figure out that he wasn't even in the same universe. That was a great twist. I also love how time fixes the paradox for Harry. I've read it about four times now and I'm still not sure how much Severus actually tried to plan. Any hints? I would also love to see another one-shot written where Harry tells Severus more about his childhood, maybe the Halloween that the Potter's don't die.
