The map is calling again and this time, it is calling just Starlight Glimmer to Canterlot Castle—much to Twilight’s shock. It turns out that Celestia and Luna are not getting along as they are not appreciating what the other is doing. Things come to a head when Starlight impulsively switchings Celestia’s and Luna’s cutie marks.
With the spell due to last 24 hours, each agrees to take on the other’s duties for one day with Starlight observing, who is being observed via music box doll by Twilight (and her freak outs are not helping). Luna finds it much harder than she though to smile for most of the day at her subjects and help placate fears of timberwolves (which she doesn’t do well) and resolve differences between representatives of cities (which she does well after three hours).
Celestia goes into the dream world and finds Starlight having a nightmare over what she has done and fears Nightmare Moon will return. She does in the dream, but also appearing is Celestia’s alter ego in Daybreaker. Luna’s also having a nightmare about the children whose fundraiser was ruined when Luna couldn’t keep her smile on forever. Both gaining an understanding of the other’s duties and making amends, Celestia, using Luna’s powers, defeats Daybreaker and they all return to the real world. Starlight is commended for being bold enough to do what she did—hence the map called her—and her mission is accomplished (though Twilight wants a full report).
Now, we’ve seen Starlight try to use magic to solve a problem to disastrous effect. Here, almost the same happens here, but the show does well that that impulse may actually be the appropriate method here. The map doesn’t call just anyone for a friendship problem. It sends the pony or ponies who it thinks is best equipped to handle it—even though the pony or ponies are unsure themselves. Starlight is filled with regret at times, but she was also the one most likely to be bold enough to do such a thing as switching cutie marks.
As for the Royal Sisters, we’ve seen hints that they don’t get along 100% of the time in “Slice of Life” and the comics, but here it is in full force. This was the kind of episode fans have wanted for a long time and they were not disappointed in the slightest.
Those in Canada who saw the episode on May 20th will attest to that as those who saw it on Discovery Family, today. It was a super episode that saw development for characters who have not had some in a long time. Twilight as a music box ballerina was hysterical as was Starlight’s reactions to it. The climax was also some of the best animation the show has had in the series.
Some will still have an issue that Starlight impulsively used magic again to solve a problem, and for awhile Starlight fears it has been for the worse once again, but this time it was the right call this time—which is perhaps why the map called just her. It’s another jewel in Season Seven’s crown.
