I had this dream before season two even began on the Hub. So when "Its about time." aired Petina was a bit put out. I'll posted her commentary about it later.
After the rather long stressful but informative day spent with Celestia and Luna getting Paynes Gray, my own and Petina's story spelled out in detail [link] I was rather drained from whole experience. Since we were going to figure what to do about the Lord of Shadows [link] , Celestia suggested that myself, Twilight, Petina, and Spike simply stay at the palace so it would be easier to meet.
We all agreed but Petina asked if she could return to Ponyville for a short visit to as she put it "Acquire some equipment that could assist us in our upcoming adventures." She said it would only take a couple days but would provide no additional details. Celestia agreed to her request.
A coupe days later Petina returned with Rarity and a pile of garment bags. Inside were Petina's secret weapon! Now Petina is of the opinion that some type of covert operation would be necessary for us to defeat the Lord of Shadows, and covert operations are invariably more successful when the female members of the group are wearing slinky tight black outfits. Kind of like what Photo Finishes female assistants wore only in black. That is where Rarity came into the equation.
It is a credit to Rarity's skill that she was able to turn out such wonderful work in only a couple days. Although Twilight was a bit disturbed by the fact that she knew the Princesses measurements off the top of her head. What bothered Twilight even more was the fact that Petina's hedonistic little mind cooked this scheme in the first place! These were the royalty of Equestria and she very was uncomfortable with the way that little white unicorn was eyeballing the two sisters. Her mind was further disturbed by the knowledge that Petina had plans to make similar outfits for all of the Elements of Harmony in case they were needed to defeat the Lord of Shadows. Petina thought that Twilight would look quite nice in one these outfits.
Celestia had to agree with Petina that the suits did flatter her figure; especially her flanks. However much to Petina disappointment she declined her outfit. Luna on the other hand was intrigued by her outfit and decided to keep it. Maybe not for their current crisis but she thought she could find some use for it in the future. This set Twilight off on further bout of anxiety as if she was watching the very decline of Equestrian civilization before her eyes!
Rarity offered little comfort to Twilight's soul when she stated that she saw no problem with the outfits. They weren't colors she'd chosen but she'd been working on spec from her client, Petina, and Petina's bits were just as good as anyone else. Besides Luna was a young mare now and she could make her own decisions. Twilight needed to relax.
