Gotta include the artist comment on this one:
 
This moment in my Equestria dreamscape is not current ongoing dream/story arc but occurred last night, but I thought folks might find it amusing.
 
When I become ill I will often have dreams where I am sick in them to. Having been under the weather in real life, which really sucks if you’re a weather pony, I found myself with a bad case of the blahs in my Equestria dreamscape. So I laid in bed while Petina periodically came in and checked on my condition. It was market day so Carousel was out running deliveries, and Petina was in and out of cottage running short errands.
 
At one point I heard a knock at the cottage door. Petina answered it and I could hear somepony entered the cottage. I could not identify the new pony through closed door, but muffled conversations went on for awhile. Eventually drifted off to sleep again.
 
A while later I awoke to the sound of the bedroom door opening. Much to my surprise instead of Petina or even Carousel walk into the bedroom it none other than Fluttershy. Even more surprising the chiffon yellow pegasus mare was dressed in this fetish nurse outfit. This had Petina written all over it. Fluttershy came over to my side of the bed with a worried look on her face.
 
“Um, Sky Brush how are you feeling? Petina said she needed to run up to Canterlot on some important business, but she didn’t want you left alone since you’re sick. So she asked me to take care of you. Is there anything I can do for you?”
 
I just stared at Fluttershy. “Where did you get that outfit?” I had my suspicions but I wanted them confirmed.
 
“Oh Petina gave it to me!” Said pegasus mare. “She had all this stuff waiting for me when I arrived.” Fluttershy looked at the outfit. “I’ve never seen the nurses at Ponyville Hospital wear anything like this, but Petina said it was quite common in Manehattan. Is that true Sky Brush?”
 
I just stared at her for couple seconds as my brain digested the scenario Petina had left me in. Then I nodded my head.“Yeah in some parts of Manehattan.” Where or how Petina had put together such an outfit for Fluttershy was something to ponder later.
 
That seemed to put Fluttershy at ease. “Oh, okay. Well I’m going to make some tea. Would you like some?” I nodded my head, Fluttershy smiled back. “Okay I’ll be back in a jiffy! You just rest and I’ll bring it in.”
 
Then she turned and trotted out of the room. I laid back and stared up at the ceiling. When Petina got back I was going to have a little talk with her.
