Excellent story you've got going here. So nice to have a time travel story with more than one chapter that takes place in the future. Funny...I'm actually guilty of doing the one chapter time jump thing.
That being said, I'm looking forward to seeing who goes into the past more than anything else...that and the pairings, though this doesn't strike me as an overly shippy fic, I do hope we get to see a tiny bit of it.
