Supernatural Reveals The Winchesters Have Always Used The Bunker Wrong!

In Supernatural's season 15, while trying to fix their Bunker, the Winchester brothers unleash a Wood Nymph named Mrs. Butters who reveals the true potential of their home. The Winchesters have been limiting the power of the Bunker on "standby mode," but Mrs. Butters infuses it with magic, giving it an upgrade and features such as a monster radar and an inter-dimensional geoscope.

However, Mrs. Butters is ultimately relieved of her duties, and the Bunker returns to standby mode. The episode answers long-standing Bunker mysteries but hints at an unhappy conclusion to the series as the upcoming battle with God looms.
