It had been a while since Twilight Sparkle last visited the alternate world. So she pops in to catch up with the human alternates of her Ponyville friends. But things seem different and there's a familiar vibe in the air. So when she hears it's Valentine's Day, she naturally has questions to how it compares to Hearts and Hooves Day. Good thing Flash and the girls are there to help her.
(Takes place between the Equestria Girls movies Rainbow Rocks and Friendship Games)
