Twilight and her friends now want to help Starlight find her long lost foal, while trying to puzzle out just how a mother could not know her own foal. Starlight meanwhile is trying to decide whether to bury the past, or drag it all up once again. Both will be painful, but the question remains. Which one would hurt the least, for all involved?

Several truths are revealed, and motivations are uncovered. When everything is laid bare how will everyone react? Will Starlight's life be turned upside down, even in this time of change for the former villain?

Midnight Sparkle, Twilight Sparkle's distant ancestor, wakes up one morning to find that she's traveled forward in time several hundred years. Now she must try to get home while enduring an Equestria that is nothing like the one she knows.

That, and a ten year old with a fondness for painting animal skulls pink living with her great-great-great-great-great-great-great... etc. granddaughter poses some unique challenges of its own, even if there are those around Ponyville who are willing to become her friends.
