Celestia had been eating her lunch, a chocolate and strawberry swirl shortcake, when she heard a screech from upstairs before the sound of glass breaking permeated throughout the castle. Shortly after a rather disgruntled Luna stormed into the dining room while Celestia calmly finished off her cake. "Is something the matter Luna? I'm not used to seeing you up so... late."
"Is something the- Of course something is the matter sister!" Luna barely used the royal Canterlot voice and yet the guards around the room still held their ears for none of them could handle it when at full power. "We- I was simply sleeping in my chambers when some batpony I've never met storms in and shouts our- my name!"
Celestia sighed calmly and stood up, walking over to comfort her sister. "Do not worry Luna, I am sure he was nothing but a fan of your night that wished to express his gratitude." It still made Celestia happy every now and then when Luna had found more and more ponies who enjoyed her night where none would a thousand years ago.
"That is not all dear sister, he was also wearing a shirt with mine image upon it that proclaimed his affections! I hath never seen such a shameless batpony, and I make sure to keep track of all those whom walk in the night." Celestia just cocked an eyebrow while Luna blushed up a storm.
"So you know all of the batponys in Equestria?" Luna nodded hurriedly, "Yet you've never met this one before?" this time she shook it. "Then perhaps he is from outside of Equestria and is merely visiting, did you make sure to greet him kindly?"
Luna moved away from her sister and kicked her hooves idly while Celestia sighed, "What did you do sister?" She heard Luna mumble a bit before putting a more stern tone in her voice, "Luna, what did you do?"
"We may or may not have... bucked him out of the window." Luna giggled awkwardly while a few guards couldn't help a giggle themselves, until Celestia glared at them slightly.
"Luna, is your room not in the tallest tower?" Luna got a bit shocked at this and nodded once more. "And which window did you buck him out of?" At the word South Celestia groaned and moved towards her room in he castle.
"Where art thou going sister?" Luna called out worriedly.
"I will be writing a letter to Twilight, telling her to search for the poor pony around Ponyville so that we might make amends." Quickly she went to her stack of paper and grabbed a quill in her magic as she wrote out her letter.
"But sister, how doth thou know of his location?"
"Luna, from where you bucked him from as well as the amount of power you put into your hind legs I wouldn't be surprised if he ended up in Zebrica."
