Again, sorry for any bad english!
After a very fast train trip to Canterlot Castle, it's so much bigger then it was 800 years ago, “Wow... the future is so awesome...” Sweetie Belle shouted as her voice echoed up the castle, “Princess Cadence, Welcome back to the castle, may I take this filly off your hooves?” a guard asks, “Why in Equestria would I do that?” replied Cadence, “Sorry Princess, it's rare to see you with a filly who is not known” replied the guard with sweat coming down from his forehead, “Uh... Princess, Luna is here...” another guard tells Cadence, “She's waiting for you in the main hall”, “I'll be there in a minute, I need to sort 1 thing out before I can see anypony at the moment” Cadence replied, she tries to hide a happy grin on the way to her room, “Sweetie Belle, I'm going to need you to wait in my room for now, I'll get somepony to send you... something from your time maybe?” Cadence asks, “Um... how about something from this time if I'm going to be stuck here?” replies Sweetie Belle, “Good point, alright, I'll be back in a few minutes, then we ca-”, “Or I could see Princess Luna and see if she can help?” Sweetie Belle jogs into Cadence's line, “Hmmm, It's possible, alright, I'll walk with Luna to here, but that can be a while” Cadence walks out of the room, a babysitter comes through the doors a few seconds later.
“Luna! How great to see you, how come your here early?” Cadence asks, “Well. I am willing to accept my sisters death... what happens, happens...” Luna replies, “Funny, I just told a filly that no less then 10 minutes ago”, “Cadence, how is 'Sweetie Belle' doing?” Luna asks, “How did you... she's fine, right now she's playing with our technology, for her age” Cadence begins to wonder how Luna found out, “That's good, I'm here to stay, and unbanishing myself from the moon, I think Celestia would want me to stay” Luna says quietly under her black cloak, “Luna, she would want you to stay, and so do I, so how's life on the moon?” Cadence asks, “Well... it's like night time forever, stars slowly move while you get to look at the planet, and the sun, for as long as you want” replied Luna, “Sometimes I would love to that, going to the moon” Cadence replies with a smile.
“Anyway, why don't we go to my room? Sweetie Belle is there, might be worth it” Cadence tries to convince Luna, “I agree, it will be worth it” Luna replies, Cadence and Luna walks to Cadence's room, “Cadence... I think Celestia is alive...” Luna called out, “What makes up think that? She died right in front of you” Cadence replies, “Not that kind of alive, spiritually alive, like... I can see her, everyday” Luna quietly wonders, “Well don't worry, you're thinking about her, and that's good, thinking of good ponies makes you feel better if you think about them the right way!” Cadence attempts to make Luna have a smile on her face.
“Here we are... my room” Cadence opens to doors, and while seeing Sweetie Belle sitting on Cadence's bed crying, “Sweetie Belle, are you alright?” Cadence asks, “Yeah... it's just hard to know all of my friends and family are gone...” Sweetie Belle replies sadly, “Listen here Sweetie Belle, I know it's hard, loosing ponies that you knew for a long time, but what happens, happens... but Sweetie Belle, I can send you back to where you came from, if that makes you happy, but that could take years” Luna with a peaceful voice felt Sweetie Belle's feelings, it hurts.
"So what are we going to do?" Sweetie sadly cried, "My guess... we start, it could take years, but I know this scroll hidden somewhere on this planet, no technology nor ponies can find it, only the Royal blood can find this scroll" Cadence with a cheer, "Really? You'd do that for me even after getting you into all this trouble?" Sweetie Belle questioned, "If Cadence will do it, so will I, Sweetie Belle, I need an adventure, not being stuck in a boring castle" Luna stood.
"I don't want all of this to be taken for granted... it's just too kind to see 2 princesses help a young 800 year old filly" Sweetie Belle started to pull a grin, a happy one, maybe tears, Sweetie Belle knew she's going home, "So where do we start?" Sweetie Belle asked, "Well we'll get everything ready, you are free to explore Canterlot and Ponyville for now, we'll be gone in one week" Luna replied, Cadence nodded, both Cadence and Luna walks out the room.
Sweetie Belle, in Cadence's room, sat there, thought, 'What kind of things can I do in the future?', a guard walked into the room, "Young Sweetie Belle, is it?" the guard asks, "Yup, that's me" Sweetie Belle normally called out, "Sweetie Belle, as a citizen of Equestria, everypony must need a tracker ID to track you in case you get lost, or know where to find you, please swallow this sweet, you can chew it if you want, also, Cadence has giving up a room in the Castle for you to stay in, we'll supply you with food and water, if there is any problems, please come see a guard, good bye Sweetie Belle" The Guard walks off, and out the room.
Sweetie Belle knew she can't get lost now, she ate the sweet the guard given to her, with the lovely taste of jellybabies in her mouth, Sweetie Belle swallows and walks to the Castle's train station, before she chooses a train, she takes a look at the giant castle, "Wow... Thi-" Sweetie Belle stopped, she froze, 3 guards looked at her, Sweetie Belle was frozen solid, not in ice, just stopped like pausing a film, 2 guards run to her, to see how she is feeling.
1 hour later...
"This... is... huh? Where- Where am I?" Sweetie Belle began to get worried, "Don't worry... you're in the hospital, you just froze, right in front of 3 guards" the nurse replied, "It's a rare condition on fillies, luckily I can cure you, all it takes is a small pinch? Ok Sweetie Belle?" The nurse asked, "I guess that's alrig- Ow, that hurt" Sweetie Belle replied, "I lied, I use that to keep small fillies calm" the nurse giggled, "Ok, Sweetie Belle, you can go now", Sweetie Belle slowly walked out of the room giving the nurse a strange look.
Sweetie Belle goes for it again, suddenly a loud megaphone is set off "Alright, everypony, it is now dinner time, please go to the mess hole, ask any tour guides if you need help getting there, thank you" the megaphone message ended, Sweetie Belle saw a lot of ponies leave the big closed doors, so she decided to follow all the ponies walking, there were so many cutie marks Sweetie Belle never saw before when she was looking at everypony, Sweetie Belle sees a pony that looks exactly like her sister, Rarity, with the same cutie mark...
