Luna woke up during the day to spend it reconnecting with her subjects...but when she sees how stressed out Celestia is from dealing with the stubborn, narcissistic nobility, she instead tells Celestia to take the day off and let her take care of the Day Court. Of course this leads to Celestia being kidnapped, but given Celestia is just playing along with the kidnappers For the Lulz, that doesn't take away from the heartwarming.
The kidnappers getting jobs in the castle after being pardoned by Celestia and Luna. Now part of Ms. Fallow's job is to help sent relief to the poorer areas of Canterlot to ensure no one makes the mistakes they made.
After the whole matter is resolved, Luna angrily and tearfully confronts Celestia about not caring how scared Luna was that Celestia could've been in genuine danger. Celestia admits she was thoughtless to do that and apologizes to Luna for it, even saying she never would've done it if she'd known things would go that far.
