When Rainbow Dash finds Pinkie Pie in a sudden depressed, sorrowful state, she takes it upon herself to cheer her friend up.
But sometimes a friend doesn't just need cheering up. Sometimes that friend just needs another friend by their side every step of the way.
Not a shipping story.
(This is also rated sad, too. It just didn't let me tag 'sad' because apparently 'comedy' and 'sad' are conflicting categories.)
