Hope honestly can't say how long it's been. Time is relative, her dad used to say, especially with our relatives is the easy joke, but true. She grew up counting time by events, not dates that were meaningless when they skipped thousands of years in a second and, besides, lived in a world where none of it mattered.
These days, time matters a bit more. After all, there are people to share it with and reasons as well as actual seasons. Still, even with quiet moments between adventures, her time isn't that much less distorted than it had been on the Barge. Especially with the time travel, dimension hopping, folds in reality and occasional coma that left her a not-quite-intangible being that absorbed the internet. ...Perhaps it's true that her life is a little odd.
She doesn't know how long it's been for Tris, either. After all, Tris had had the barge and her plans afterward to deal with before returning to her home. But Hope is confident that the scans she took and her experience with dimensions and time mean she's found the right version, and even more confident that, no matter how long it's been, it'll be good to see her sister again.
