Luna is unnerved by the previous day’s dream, and believes that the only thing that can help her now is the magic of friendship. Luna asks Twilight for permission to travel with her back to Ponyville to meet Twilight’s friends the next day, and Twilight agrees. Twilight goes to bed earlier so she can travel home in the morning, but still stays up long enough to watch Luna raise the moon. Slight timeskip to the next morning, where Luna and Twilight go to Ponyville and Twilight starts introducing the rest of the Mane 6. From here, you have complete freedom to describe Luna's experience with Twilight's friends. Seriously, go nuts.
The day ends with Luna staying at Twilight’s house, where she raises the moon for Twilight again. They stay up together for a short time (not as long as the previous chapter, it’s been a long day), Twilight goes to bed, Luna stays up until Twilight gets up. Twilight insists that Luna sleep in her bed.
