A few months later, the spell runs out and the nightmares return but Luna quickly recasts the spell upon herself. "There," she sighs. "That was a close one." She then goes out into the main hall where she meets with Celestia and the two then head out on their annual royal visit to YakYakistan, leaving Twilight to rule in their stead once again.
After several hours of flying, the two sisters touch down in YakYakistan and are greeted by Prince Rutherford and his son, Rutherford II. "Hello Princess Celestia, Princess Luna," say the princes with smiles on their face. "It's good to see you again."
"And you," respond the sisters as they take turns sharing hugs with the two yaks. The four then enter the main courtyard of the village. There, the four continue their conversations.
"The town has grown so much," sighs Luna. "I'm impressed."
"Yeah, thanks to your friends, we've been able to rebuild faster than we'd ever be able to rebuild alone," responds Prince Rutherford I. "Applejack and Rarity especially have a knack for building and Pinkie and Twilight for refurbishing and organizing."
"Don't I know it," replies Celestia with a smile and a laugh.
The four then enter the main castle, which has been newly rebuilt and restored. The four then sit down to lunch. As they eat, they can't help but do just some friendly chatter and crack jokes and share laughs and have an all around great time. After lunch, Rutherford pulls Luna to the side. "I can see something is bothering you, Princess," he says. "What's wrong?"
"I've just been having nightmares lately, I'm fine," responds Luna. "Thanks for asking, though. I appreciate it." The two then go and catch back up with Celestia and Rutherford II. The royal sisters came just in time for the YakYakifest. The royal sisters enjoy the festivities alongside the two yak rulers, especially Luna. This makes Celestia glad and she doesn't even realize that Luna has started having nightmares again or even recast the spell and that has Luna relieved above all else.
That night after the festivities come to an end, the two are shown to their guest rooms and turn in for the night. While Celestia sleeps peacefully, Luna can't help but feel guilty for not telling Celestia that she had to recast the spell upon herself. She finally resolves to tell Celestia in the morning before the princes come and fetch them for breakfast. She then falls fast asleep and is not disturbed by anything but her own guilt and to her, that is better than being awoken by the nightmares she used to have.
The next morning, Luna goes over into her sister's room. "Ti," she says, "I've started having the nightmares again. I recast the spell upon myself before we came here. I just thought I'd let you know."
"Well, thanks for letting me know," responds Celestia with a smile. "Now, who's ready for breakfast?" A few minutes later, the two are grabbed by the princes and they go and enjoy breakfast together, all the while, Luna feeling good now that she's gotten the guilt off her chest.
