Thread 257 Edit
 During a conversation with Miles Delight, Alterjack silently recalls the time Rarity annoyed her Diamond Dog captors into letting her go and giving her all of their gems. [Q] "Look at all the gems I relieved those dimwitted canines of through the sheer cunning of my femininity, darlings! LOOK AT THEM! OHOHOHOOO!"
 Rarity starts of saying sse and Arana need to talk. Arana's worried she's being fired, saying "I knew I shouldn't have put up that fly catcher in the bathroom." Rarity does a double-take and asks if the flycatcher was "what that cobweb was" before asking why she's catching flys. "Because they'd fly around otherwise!" Rarity points out that's not what she's asking, but Arana asks why else would she make one for if not to keep flys from flying. Rarity skips over the question, stating "I'm just going to move on quickly before you can confirm my worst fears." To that, Arana says "You're not pregnant!" "Second worst fears." "You're not that old yet!" Rarity puts her hoof down and steers the conversation back to what she wanted to talk about, namely how Arana has been altering her designs. Arana's confused, since she's never altered them, and Rarity explains the web-silk clothes become see-through when wet. When Arana says she never noticed that since she never gets the clothes wet, Rarity briefly panics and questions whether Arana cleans the web-silk clothes. " I dry clean them! They're dry clean only ya' see. I'm pretty sure. I don't know for certain cause I just saw a suit with 'dry clean only' on the top and it seemed like something all the rich clothing had, so I put that on them!" Rarity's fear of unclean clothes being sold put to rest, she next insists that Arana needs to test these sorts of things because "otherwise someone might go to a party and stand too close to a fountain and show the whole world her see through flank covering!" Rarity soon makes it clear that she's speaking from experience. Confused by this, Arana points out that ponies are always naked but Rarity cuts her off and insists it's the principle that matters. With that, Arana reiterates the lesson she's supposed to takes from this: "So, dunk stuff in water to see what it does?" "Yes," Rarity exclaims. And at that, Arana grabs a nearby bucket and dunks it on the mare's head. "Wow, your shampoo turns funny colors when it touches mop water." Rarity has some regrets...
