Blue Sky AU - Its Wheatleys first Christmas outside of Aperture, but while the town of Eaden is bustling with holiday cheer, dark times also begin to resurface and haunt Wheatleys memories. Will Wheatley be able to face his inner ghosts? Some Chelley fluff also ensues. Inspired in part by the song Peppermint Winter by Owl City and A Christmas Carol by Charles Dickens.
