My entry for Indigo Eclipse's New Year's Shipping Challenge!

After an unfortunate, though well-meaning, change in dialogue by an eyepatch-sporting time traveller, Twilight Sparkle is left with an unscientifically-possible other her in her library!
The mare from the future cannot get back, and is understandably upset at the prospect.
But through their efforts to find a solution, and by (awkwardly) helping each other to see just how worthwhile they both are, might the displaced mare find a reason to stay?
