When sunset learned about the memory stone as well as how little time she had left to save her friend's memories from oblivion she rushed to find and undo it was too late. With the unexpected, but welcome help of Trixi she found the culprit in one Wallflower blush. Yet when she confronted the vengeful teen who would see no reason Sunset made the choice to save her friends as well as prevent the memory stone from being used ever again.

Through her selflessness came at great cost.

Now her friends both in Equestria and Canterlot high have to deal with a side of Sunset that hadn't been seen since Celestia first took her in as a student. Not the prideful, arrogant mare who charged through the mirror at the false belief of power. But a scared filly as they realize the memory stone does not work exactly as they thought it did as they try to get their friend back.
