After Nightmare Moon was purged from Luna's body, it left her completely and utterly weak. Struggling to perform even the most basic of spells, she has been spending a lot of time in her quarters trying to regain her strength, but recently she's been dealing with horrifying nightmares that assuage her night after night, each worst than the last.

After a particularly bad nightmare, Luna starts to lose hold of what is real and what is fake, and it is up to her caring and loving sister to help her through her ordeal.

It had seemed like a good idea at the time, until Sunset actually read what Twilight wrote in her letter. She'd already said yes to seeing Celestia again, and she wouldn't go back on her word. As long as she remained convinced that this was a good idea and that it would all end well, she could get through it without a problem.
