I have to say, Harry telling Ron that Draco is really his long lost twin sister had me laughing so hard I thought I was going to have an aneurism.

A very informational chapter. I like this take on time travel, it's not and endless loop so nothing's a forgone conclusion. It makes the story work, sure, but I also just like the different take on the whole problem, because lots of fics use time travel, but this is a very unique way of looking at it. I like it very much. I also like that Father uses gravity and other things from physics instead of magic. Makes the whole thing even cooler than in would have been.

"Now, fifteen years before Voldemort comes up with the concept, there isn't a person, artefact or spell on the planet that can follow Father."
- I think "Voldemort" in this instance should be changed to "Luna" or "Doc". Luna is the one who created Gatekeepers, not Voldemort. She's the only who knows how GM works.

"Same principal."
- This one should be "principle" rather than "principal".

Now Harry's extreme anger at Dumbledore makes more sense. Idealism can be a great thing in peace time and more than tragic in times of war.

Clever, clever, CLEVER beyond clever twists and fabrications of a future knowledge back to save the day.

Well done.

Giggle.

So, Harry's bringing in the twins, is he? Kickass.
