Great story. Really I loved it!

Haha... this is a good story! I love it! I always wanted a Back to the Future IV. To be true, I wanted it to reach at least until 6 or 12. Anyways, your story is good and it is nice how you made time-traveling and the time-conflicts that go with them be in order. Sometimes I've read stories that totally have parts unlinked to the other. And this could be a problem especially if the story is something like Back to the future. Anyways, good work! I'll keep myself informed just in case you ever updated.
