That's a terrible choice, Lulu!
"I'm bored." The words came from Luna, who was laying down on top of Celestia, and had her head resting on her sister's barrel. The two of them were exhausted from today's work, and so, they did the only thing that would begin to make them feel better; cuddling with one another on a sofa while talking about each other's day (both of which happened to be quite boring). It was working, somewhat; the downside was that there wasn't much to actually talk about, so the ever-increasing threat of getting killed by boredom was creeping up on them.
"So am I." Raising her right hoof up, Celestia began running it through Luna's mane, admiring how her sister's mane caught the light. Caught pretty much everything, actually. Her sister's hair was like a brick wall.
"...So why aren't we doing anything?"
"You tell me."
A cheeky, short reply was given to Celestia. "No."
Lazy, Celestia thought with a slight frown, you expect me to think of something for you? Fine; there's a theoretical question I've been wanting to ask anyway. "Fiiiiiine, if only to relieve our boredom somewhat. If you had to pick a pony, any pony, to become an alicorn like us, who would you pick?"
Luna lifted her head up slightly, interested in her sister's question. "Hmm. That's kinda interesting, Tia. I'm not being serious with this answer, but Pinki-"
Celestia was quick. "No."
"I figured as much. Well...I'd have to say Rainbow Dash."
Obvious choice, coming from you, Lulu, but seriously? "Excuse me for saying this, please. That's a terrible choice, Lulu! Seriously, all Rainbow Dash would do is sonic rainbooms all day and complain about suddenly being too cool for the wonderbolts. She also would probably not do any political work required within the castle, and would most likely cause an international incident, what with her attitude of hers. You don't pick her because you have a crush on her."
With a sigh, Luna looked at her sister with a slight frown. "I do not have a crush on her, and oh, sure, like you have a better choice in mind."
"You hide your feelings very poorly, and I do, actually."
Whatever. Totally don't have the hots for Rainbow Dash. Luna lowered her head back down onto Celestia's barrel, feeling too tired to keep it up anymore. "Name?"
A slightly happy Celestia immediately thought of the only pony who she would pick to take this theoretical position. Only the most suitable pony, of course. "Twi-"
Groaning, Luna gently slapped her sister across the face. "Now you're just playing favourites."
Smarting from the slap, Celestia rubbed her muzzle gently while scowling at Luna. "What?"
"Tia, she's not a serious pony you can honestly pick; she can't be, if you have any sense at all, which I doubt you do. She panics easily, thinks too hard about some subjects, is known for being very OCD, and she is the most powerful unicorn I've seen in a long time; if we theoretically picked Twilight Sparkle to become an alicorn, chances are she'd start a war because some ponies don't like hash browns. I've seen Twilight eat hash browns. It's not pretty."
...That's true. Especially the hash brown part. "Lulu, think of the possibilities, though!"
Luna scoffed at what her sister said. "What possibilities? We'd be trying to stop her from going to war against our own country, specially the ponies that don't like hash browns. That's a possibility I don't want to experience because potato prices will probably raise everywhere. Oh, and ponies would get hurt."
"Well, being so organized, Twilight could do all of our paperwork!"
Yes that'd be nice, but you're missing the point, Tia. "...While putting us into a war; I really don't want to smack ponies around with those giant pretzel sticks our soldiers use as spears. You're blind to her faults because she's your favourite, Tia."
"Well...I could argue that Rainbow Dash is your favourite, as well."
"True enough, Tia."
A new voice began speaking, off towards the side. "Oh, you two look cute."
Celestia looked at the general direction the voice was coming from to see Chrysalis, who happened to be smirking at them. "Hello to you too, Chrys."
"Hey." The changeling alicorn sat down in front of them, stifling a yawn. "Bored?"
An unenthusiastic reply came from Celestia as she gently nuzzled her sister. "Ya."
"Figured as much. I am, too; figured a walk might relieve my boredom, and it might just happen to work, assuming you two have anything to do."
"Not much," Luna mumbled, "we've just been talking about what pony we'd choose if we had the ability to turn one into an alicorn like us."
"Sounds interesting. Dumb, but interesting. Hmm..." Chrysalis was now deep in thought, and Celestia couldn't help but be interested in what Chrysalis had to say; after all, she had a vastly different personality compared to theirs. "I would have to say that the best overall pony for such a position would be Fley Truths."
Celestia's eyes widened in surprise. That's certainly not a choice I was expecting to hear. "Fley Truths, huh? Why?" Celestia stopped messing around with Luna's mane, much to the lunar alicorn's disappointment.
Chrysalis took in a deep breath before explaining her choice. "It's all a matter of perspective, really, but I think Fley Truths would be the ideal pony to chose for the job because of the fact that she already deals with the nobility and their insane requests. She also has been able to keep them in check, something that we've never been able to do and only Fancy Pants has also been able to do. Fley Truths also, like you, has a softer side, so she'd be able to easily sympathize with other ponies very well, and the large amount of bits she has doesn't hurt either, as she'd finally be able to push on through with her own projects rather than having to wait months for the chance of having it approved. Also, she makes nice waffles."
"I see. I...Wait, waffles?"
A nod was given from Chrysalis. "I visit her every now and then; she does take care of Quackum, you know, and offers me some food whenever I come by; when I tried her waffles, they were just heavenly, and I'm sure turning into a alicorn would make those waffles so good, it'd probably kill me with bliss."
Celestia's eyes narrowed in suspicion, wondering if Chrysalis was one of them. "...Do you eat them with syrup?"
With a laugh, Chrysalis shook her head. "No. Syrup is nasty."
Quickly, Luna scrambled off of a now malicious Celestia who was advancing on Chrysalis, and hid behind the sofa. "You shouldn't have done that..."
