The Horde is stealing the rebels' food. Glimmer and Adora disagree on what course of action to take against them. Glimmer gets tired of everyone following Adora's plans instead of hers. She visits Mirror Lake, where a magical reflection of herself says she should make her own plans to fight the Horde. Little does she know, Shadow Weaver has used her magic to trick Glimmer into making her own rebellion, consisting of Horde troopers. (thetvdb.com)
