Arriving at Twilight's bedroom, Sunset decided to go directly to the point.
"Twilight, can I ask you two questions?"
"Of course, what do you want to know?" replied Twilight.
"First, what is a BBBFF? Why did you call your brother that?" asked Sunset, with a confused look on her face.
"Oh, yeah. I forgot people don't usually hear that. It stands for 'Big Brother Best Friend Forever', and I call him that because it's exactly what he is to me," said Twilight, blushing.
"Hm. That makes sense. The other question is: who was that pink woman? She didn't look like she's related to you," asked Sunset.
"That was Cadence, Shining's fiancée and my sister-in-law. She's a really nice person, and used to babysit me," replied Twilight happily, remembering all the good times she spent with Cadence.
"Well, she really seems to be a nice person. Now, let's get to the main point of this visit: what will we do?" said Sunset with an eager look.
"Well... want to study a bit?" suggested Twilight, blushing.
"Twilight. I came here because I AM bored, not because I want to BECOME bored. Seriously, studying? It's summer, for Celestia's sake!" said Sunset.
"Celestia? Why did you use the school principal's name? She isn't a goddess," said Twilight, confused.
"Remember when I told you I came from an alternate dimension, and the whole 'Princess Twilight' thing?" Twilight nodded, so Sunset continued. "In my world, Celestia isn't a school principal. Well, technically she is, but that's another story. She is actually another princess. Princess Celestia is the almighty ruler who controls the Sun's movements. She is kind of a goddess. She was also my teacher." As she said that, she remembered the times when she was Celestia's student.
"Sunset? Are you alright? You seem kind of sad. Did I say something wrong?" Twilight said, worried about her friend, who was looking sad now.
"No, it's alright. I was just remembering all the mistakes I made in the past. Running from Equestria, driving everyone at Canterlot High apart, stealing a powerful magic artifact, literally becoming a winged devil-" Sunset would go on, but when Twilight put a hand on her shoulder, she stopped.
"Don't worry Sunset. That is all in your past. Your past should not define you. It isn't today. We should learn from the past in order to have a better future," Twilight said as she tried to cheer her friend up.
"Thanks Twilight. I really needed that." Sunset was almost crying, but she managed to hold it.
"Besides, you're not the only one who committed mistakes in the past. Remember how I used to be, before you came? I never knew what friendship was, until you and your friends came and shared its magic with me." Twilight was now starting to laugh. "I can't thank you enough for what you did. When I transferred to Canterlot High, I didn't expect to learn something apart from what the teachers taught inside the classrooms. If it wasn't for you, I'd probably still be alone."
"Yeah, I'm kind of awesome," says Sunset with a smug grin.
"Wow, Rainbow is really rubbing off on you. Either way, what I just said helps prove what I said earlier. Your past is not today. If it was, you wouldn't have befriended me." Twilight was now smiling more than ever.
==============
Somewhere else
==============
Pinkie Pie and her family were now on a volcano, inspecting its basalt. As she was walking, she felt something different in her heart.
"Wow. What did Sunset do to get a smile so big out of Twilight?" Pinkie said, just being herself.
==============
Back to Sunset and Twilight
==============
Tired of talking about the past, the girls decided to play a game called "Trivial Pursuit", a trivia game with varied themes.
" So, Sunset. You fell in a blue square, so it's Geography. What category will you choose? Opera, Homer, Harry Potter or Maps?" asked Twilight. She was really enjoying playing with Sunset. She proved to be a worthy adversary in this game, as she only needed a blue wedge to earn the rights for the winning question. However, Twilight already had all six wedges, so if she got the next question right, she would win.
"I choose Maps. I've got a good feeling about this one." Sunset was determined to win this game just to rub it in Twilight's face.
"Okay then, Maps, Blue question... OH COME ON!" Sunset looked at Twilight with a confused face, so she just said the question. "What is the official name for a mapmaker?
" I knew I'd get lucky! It's a Cartographer!" Sunset shouted at the prospect of winning. But it was too early to celebrate, since if Twilight got the next question right, it would be Game Over. "Can you give me the blue blue, please?"
"Okay then, just let me roll the dice and end this game now." Twilight picked the blue wedge and gave it to Sunset, then picked up the dice and rolled it. When her piece fell on a green square, she could already feel the taste of victory. "YEAH, SCIENCE!"
"Okay, so now we have Opera, Homer, Harry Potter and..." Sunset made a pause to replenish the card she chose earlier. "Diamonds."
"Diamonds, I choose you!" Twilight shouted like an anime character. "Go on, read the question.
Sunset shaked her head and tried not to laugh at Twilight's reaction. "Okay. What element are diamonds made of? OH GODDAMNIT!" Sunset was almost flipping the board, but if she did that, she would be a bad sport.
Twilight tapped her chin in thought with a tiny smile she attempted to hide. However, Sunset shot her a frown, and with a smile, Twilight recited, "Diamonds are an allotrope of Carbon, the sixth element in the Periodic Table, with an Atomic Mass of 12 units, which means that One Mole of Carbon has a weight of 12 grams"
"Come on Twilight, you know perfectly that saying "Carbon" would be enough. Why do you need to show your knowledge so much?" Sunset was annoyed, but she found it kind of funny. "Anyway, has anyone ever beaten you on this game?"
"Well, I haven't really played this game that much. Most people refuse because they know they'd lose," Twilight said, looking like Rainbow. "But, from all the people who played with me, you're the one who got closest to winning."
"That's actually a relief. One of my favorite sayings is 'If you're gonna lose, then at least lose to a champion', and that's just what I did," Sunset said pridefully.
"So, what are we gonna do now? That game only lasted 10 rounds, and I don't want to play again. Losing once is acceptable, but twice, even if against a champion, is too much." Sunset was now thinking about things they could do, when Twilight interrupted her thoughts.
"How about we just talk a bit? I kind of need to relax after thinking so much. I was actually worried I'd lose against you." Twilight's words surprised Sunset so much that her eyes widened just like two soccer balls.
Sunset bowed as if she was in front of a monarch. "Why, I'm flattered, O Great and Almighty Twilight the Wise." Sunset stuck out her tongue to show Twilight she was joking.
After that, Shining Armor appeared on the door. "Hey Twily, Cadence made a snack for you and your friend. She asked me to come here and call you two. Want to go now?"
Twilight's stomach growled. "I think we'll go now. Let's go Sunset?"
"Alright. We don't have anything to do, and we could think about it while eating," said Sunset.
When they arrived at the kitchen, she found Cadence waiting with some sandwiches.
"So, you're Sunset, the girl Twilight talks about so much," said Cadence while the girls sat down at the table.
"CADENCE!" Twilight's face was getting red as she heard that.
"What? You do talk about her. Anyways, I'm Cadence. Nice to meet you, Sunset," she said looking at Sunset, as if evaluating her.
"You too. Twilight told me you used to be her babysitter. How did you manage to be friends with a girl so antisocial? No offense, Twilight," said Sunset, smiling.
"None taken. I know I used to be really reserved, but inside my family, I was just like I am with you and the others nowadays. Anyways, Cadence was already Shiny's girlfriend, so she was already part of the family," said Twilight.
"But don't act like you didn't have any weird moments." Cadence was now looking at Sunset again. "Once, I took her to the park to meet other people and she ran off to hide under a bench. It was really funny to see her thinking nobody could see her there."
"I can imagine that happening. But seriously Twilight, under a bench? You could think of lots of other places to hide. Anyway, I think we should eat now. These sandwiches are looking delicious." Sunset picked up one of the sandwiches and took a bite. "Not only looking, but tasting as well. Did you make them by yourself?" she asked Cadence.
"I don't wanna brag, but yes. I made them from scratch. However, Shining bought the ingredients, so I think he should get some of the merit too," answered Cadence.
Twilight also picked up one of the sandwiches, and once she took a bite, she started eating one after another.
"... What are you doing? Are you that hungry?" Sunset asked, confused.
"Whoops. Forgot you were here. Sorry, but I can't hold myself when it comes to Cadence's food. She's just too good." Twilight then slowed down, but continued eating lots of sandwiches.
After everyone finished eating, Sunset and Twilight decided they would stay in the kitchen with Cadence chatting for a while.
"So, besides that park incident, what other shenanigans did you have to deal with as Twilight's babysitter?" Sunset asked Cadence, who was now trying to remember something.
"Oh, there was that time we created a 'Joke Contest" between the two of us and Shining Armor. The best one she could come up with was 'Why is the corner hot? Because it's 90 degrees!' and she couldn't stop laughing." Cadence was now trying to hold her laughter.
"I was young! I didn't know many other jokes!" said Twilight, angrily.
"Hey, you know what? Why don't we have another joke contest now? We don't have anything better to do, and it's a fun way to pass time," said Sunset.
"Yeah, it's a good idea. Maybe this time you can win, Twilight. Shining, wanna participate?" asked Cadence.
"I think I'll just watch. I don't think I can win against you," said Shining as he sat down on the sofa.
"Okay. We have 5 minutes to think of the best joke we could have, then we will tell them in alphabetical order, so it's Cadence, Sunset and then me. Whoever gets more laughs wins."
With the rules established, the girls started thinking of the jokes they would say. Passed the five minutes, Cadence started telling her joke.
"Which of the American presidents was the least guilty?" When none of the others tried to guess anything, she completed the joke. "Lincoln, because he was in a cent. Get it?"
Sunset laughed slightly, and so did Twilight. Shining, however, was laughing like a hyena.
"Well then, I guess it's my turn. How do you make Apple Pie? You get 3.14 apples and bake them!" Twilight and Shining were laughing nonstop now, while Cadence was only a bit.
"I guess it's my turn now. What do you call a weapon made of NaCl?" said Twilight, trying to stop laughing.
"And of course, she makes a science joke. Who could guess?" Sunset said sarcastically.
"Don't interrupt me. Do you want to hear the joke or not? Anyways, what do you call it? A-salt rifle!" Only Twilight was laughing at that one. "Hey, it was a good joke!"
"Well, better than the 'corner' joke at least," said Sunset. "So, I guess I won."
"Yeah, your joke was really better than mine. Not even Shiny laughed when he heard it," said Twilight, glaring at her brother.
"Can't blame me, it was a weak joke. But Sunset really won. What should be her prize?" asked Shining Armor.
"We can think about that later. Either way, it was a fun contest. Now, what shall we do, Twilight?" said Sunset.
"Well, if it's OK with you, can we go back to my room? I have something to ask you," said Twilight, shyly.
Sunset agreed and they started heading towards Twilight's room. Little did she know, what she was about to hear would change her life.
