Twilight Sparkle has been working herself into such a state of fatigue that Celestia has ordered her to take a five month vacation from her studies and has given Spike the assignment to ensure that Twilight relaxes. A lot can happen in five months.
This story, though labeled as number five, was actually the first MLP story I wrote. I greatly enjoyed writing it and I hope you enjoy it too.

The friends we take for granted are often the ones that leave the largest impact on our lives. When Spike falls seriously ill with a mysterious disease and the ponies strive to nurse him back to health, Twilight Sparkle comes to grips with this very realization about her number one assistant--and friend.

EDIT: So this little story made it on Equestria Daily on 10/8/12. Now please excuse me while I pass out on Rarity's fainting couch while murmuring a soft Fluttershy "...yay."

Being a princess is stressful, but your peers and friends can certainly help.

That was what Twilight had in mind when she invited Luna over for tea one afternoon. A relaxing, friendly meeting between two fellow princesses where they can commiserate and share their experiences. An invitation to a stronger friendship than they had before, offered to a pony displaced in time.

What she got was an uncomfortable assertion about her relationship with her number one assistant, Spike. One that she is having difficulty refuting.
