Sunset Shimmer has been having bad pains that she wrote off as more lovely bonuses of her human form having a period every single month. The truth is much worse though as she finds out and tries to keep it from the group of friends she wants to be a part of, even if she tries to pretend she doesn't want anything to do with them a lot of the time. Her secret will cost her her very life.

Fluttershy has her own secrets, secrets that can either save Sunset or doom them both. Secrets that will show that not only did she bend the two most important rules in her life, she completely destroyed them. If she tells Sunset, she could risk bringing death down upon them both.

And finally Celestia herself, she always reminded Sunset of her ex-mentor from Equestria. It wasn't just her looks, but the way she acted at times. How she seemed as if she had lived for centuries much like her counterpart which was impossible as humans were not immortal. Celestia seems very worried about Sunset and wants to help herself, but when she learns someone beat her to the punch, will she offer protection from others or do what her job demands of her?
