Twilight Sparkle has quite the task ahead of her. Not only have her friends from the human world called upon her to help deal with the threat of the Sirens, but she also has to come up with a whole new magic in order to do it. Naturally, such a spell will take a long time to make, and she works well into the evening to accomplish this goal. But, on her way out of the school, she comes across three faces she really didn't want to meet.

In the end, she realises that her enemies have chosen a very special plan to deal with her.
