The Mane 5's newest friend Hilltop Glide is usually open about a lot of issues to them, except one. One particular day, he starts acting so reclusive it sets off a lot of red flags that they couldn't ignore. They set out to investigate what got their friend upset. Are they prepared for the truth?
Note: Though I chose the Mane 7 tag, Twilight and Sunset are absent from the story.
Edit: Fixed a few grammatical errors. Let me know if you see any more of that
