Yona is plagued with many nightmares regarding her feelings for a certain Earth Pony, as well as a problem regarding a certain changeling. And there's only one princess who can help the young yak.
Will the future know about us or will we be forgotten and erased from history? Twilight couldn't allow this to happen. And so, she devises a masterplan to preserve the friendships of all ponies and creatures for Equestria's new generations.
Leaving Carousel Boutique the morning before he and Yona are set to debut their latest fashion line, Sandbar finds himself thinking. That's the sort of thing that usually doesn't turn out well for him.
The new fitness and outdoor skills program at the School of Friendship needs an instructor. Although more than willing, Rainbow Dash is too busy to accept the position. So, she suggests an unexpected alternative for the job.
Sandbar is a bit insecure about the size difference between himself and his wife, Yona. However, he learns an important lesson from a friend about what it really means to be a stallion.
Silverstream, Teramar, and Ocellus opt to give Yona swimming lessons so she can stay afloat. It's a task that will be easier said than done, considering Yona's clumsiness and aversion to water.
(Takes place right after "She's All Yak".) Yona is still wondering why Sandbar invited her of all creatures to the school dance, so she decides to ask him. His reply is simple, he loves her. But Yona is still confused and uncertain.
