Sepia was in the music room when the Jade Winglet and Silver Winglet were put together. She danced along with Anemone, Turtle, Kinkajou, and Boto to Qibli's drumming. During the assembly, Sepia may have been the broad-shouldered MudWing Moon hid behind, although this is not proven. Sepia was later shown tramping down the mountain side with Newt to find somewhere cool and muddy to lay down with some other MudWings.
Sepia attends a history class along with the remnants of the Gold and Jade Winglets. When Winter defends Darkstalker from being a murderer, Sepia calls his sister a murderer and questions his judgement. When Winter responds that Sora was the one that blew up the history cave, Sepia calmly responds that it was because of Icicle's actions in the first place. Qibli has to step between the two to stop a fight and the class gets back to studying after an interjection from Webs.
