After coming to live in Ponyville and discovering the joy of having friends, Twilight found a new appreciation for Hearth's Warming and its story about companionship keeping the cold at bay. It would come as a surprise to her to learn that anypony could think she's forgotten the spirit of Hearth's Warming, but the new Princess of Friendship has a habit of sometimes missing details, even when they're right under her snout.
On Hearth's Warming Eve, Twilight is visited by three ghosts who take her on a journey across time to show her what she's almost missed.
