Day 3 (afternoon).

"Passion~!" a certain indigo princess called for her love in a sing song voice. When she didn't receive an answer she immediately knew the pony she was looking for was once again submerged in books, unable to hear her call. Just like a certain lavender mare. An idea popped into Luna's head. She approached the focused mare slowly, careful not to make any sound, and right next to her ear she whispered... "Chocolate"

"What?! Where!" it had worked. Passion looked frantically around the room with sparkling eyes, looking for anything resembling the delicious and famous dessert.

"Well, I finally got my mare back!" Luna said in a false hurt tone, rolling her eyes.

"O-oh! Luna! I'm sorry..." she muttered, her head hung low in shame. Luna levitated the books she was reading back into her bookshelves and approached Passion with a loving gaze, sitting next to her and wrapping a soft indigo wing around her.

"I understand you are worried, and that you want to know more about yourself." she caressed Passion's cheek, which had some bandages on, with a hoof "But you need to rest. Do it for yourself and... for me."

"A-alright" the injured mare nuzzled the princess' coat lovingly, her face as red as a tomato, taking a moment to inhale her love's scent which provoked more old memories to come to the surface of her mind, revealing other aspects of herself "Thank you, Luna... But it wouldn't be a bad idea to actually eat some chocolate, right?"

"Not in the least!" Luna proceeded to make the order, and then she turned back to Passion, remembering she had something important to tell her.

But she would not tell the whole story. She knew Passion would try to stop her.

"There is something I wanted to tell you. You see..." Luna began, behaving like a little filly trying to confess to her parents that she had eaten the whole cookie jar. "There is a mare named... Sun Rays and another mare named Lavender. The situation is that these two mares have been showing a lot of... affection lately towards each other..."

"You're trying to match them?" Passion shot her an accusing look "You are, aren't you" Luna's mischievous grin and silence was enough confirmation for her "And how do you know this? Are you sure you're not mistaking anything?"

"Lavender is one of my most loyal soldiers, and I know quite a bit about her. Sun Rays is a researcher at the University. And no. I'm not spying them" Luna claimed calmly after detecting the implication. In that moment, the servants arrived and bowed, offering the small tray of chocolate cookies. After the servants left they resumed their conversation, Passion already munching on a cookie she held magically. "And I am very sure there is something in both their hearts. They're just too naïve to realize it." while Luna kept protesting about the two mares, a particular memory came back to Passion, and she gasped in horror.

I can't believe I partook in this!

"Alright, Luna. I understand" the princess looked at Passion with amazement. She was surprised that she had actually allowed her to nudge the couple a little bit that easily. Too easily "But please" Passion was looking at her in the eye with a serious expression "do not even think about making that love potion again!" they stared deeply at each others eyes. And then Luna broke into hysterical laughter.

"So you do remember!" the princess said when her laughter went down to light giggles.

"Y-yes..."

"Do not fret. I am not interested in destroying another kingdom." Luna assured the scarlet maned mare (who was going through her fifth cookie) still with a smile plastered on her face.

"Promise me"

"I promise" they shared a comfortable silence which was only occupied by Passion's munching, until Luna broke it again "I feel awful for that prince..."

Obviously, Luna was being sarcastic. Though she was sorry about the kingdom's downfall, watching how the earth pony prince obliviously stared at the bottle that sat at his desk in his office which had a note saying 'This will make thy romantic life less miserable', his sparkling eyes and his hopeful smile, how he offered it to the alicorn princess he was in love with, and how things had gone horribly bad was very amusing. Because, no, that love poison recipe was not in any book, specially not in any an earth pony could own; that disaster was not the poor prince's fault.

But Luna is the princess of the night, co-ruler of Equestria.

And she does have a protective and caring big sister, who is also the ruler of Equestria.

And they can meddle a little bit with history. As long as it is for the greater good, of course.

"Th-that's horrible" muttered Passion with guilt, mindlessly eating her ninth cookie. Luna looked at the plate, it only had one single cookie left. Just before the chocolate lover could grab it, Luna levitated it away from her magical grip "I-I'm sorry! I didn't realize I was about to eat them all... Wait. Why are you grinning?" without any warning, half of the cookie was shoved inside Passion's mouth. Luna started leaning slowly...

And she took a small bite of the other half. She munched, still very close to Passion's muzzle.

The poor mare was dying under Luna's provocative stare and she could do nothing about it.

She was lost inside the endless maze of the princess' teal eyes.

Little did Passion know that there was no such a soldier named Lavender, or a researcher named Sun Rays. Luna knew the two mares who were unknowingly in love with each other perfectly... Well, at least one of them, but the other one was easier to read. After all, who wouldn't know their sibling?

As Passion suffered under her princess' teasing, a certain unicorn mare suffered under her heart's confusion. But the mischievous Princess of the Night had nothing to worry about. Her plan was already in motion.

She definitely had nothing to worry about.

Definitely.

It was harmless.

No love potions, no magical artifacts. All that she did was convincing 'Tia to invite Twilight to a study session and take a free week while she took care of court so they could get time for themselves! Then everything will flow on its own! She even had Passion's approval, and the Princess of Love herself originally had the idea!

So why did she have this terrible feeling that something was going to go horribly wrong again?
