After another stunt gone wrong, Rainbow finds herself cooped up in a hospital room again. But when she ends up getting roomed with a nine-year-old colt, her stay at Ponyville General takes a turn that's worth just a little more than reading a book about an archaeologist.

Pinkie Pie has been depressed for a long time. Her business has failed, she is out of pocket, about to lose her house and feels abandoned by her friends. In a moment of desperation, she tries to take her own life, only to be saved at the last minute by Rainbow Dash.

As Pinkie continues to battle with her depression and suicidal feelings, Twilight, Applejack and especially Rainbow Dash, must deal with the fallout of her suicide attempt.

This is a tale of sadness, pain and hope, one that focuses on the impact of our actions on others.

Apple Bloom, Sweetie Belle, and Scootaloo are all friends. Together, they can do anything! They, as the Cutie Mark Crusaders, will find a way to earn their cutie marks!
But trouble arises when Apple Bloom and Sweetie Belle get their cutie marks and leave Scootaloo alone as the only crusader left.

If I have to say this story was inspired by anything, I'd say it was inspired by BlackGryph0n and Bassik's song: Crusader.

It's an amazing song, and I feel inspired by it in some ways.
