Spike left Twilight's library to go see Rarity, he was going to give her a rare gem he found in the caves, when Spike got Rarity's house, he gave Rarity the gem, Rarity took the gem with her magic, oooooh Spike! it's absolutely gorgeous! Rarity then gave spike a kiss, would you like to have dinner with me Spiky-Wiky? sure, anything for you Rarity. Rarity then prepared a lovely meal for the two of them, as they started eating, Spiked asked Rarity, What will really happen when I become a big dragon? Rarity put down her tea cup and said, well when you grow up you will... uh... you will... a vision of Spike turning into a rampaging monster brought tears to Rarity eyes, and before she could say anything to Spike, she ran up to her bedroom crying, Spike came up the stairs and knocked on Rarity's door, Rarity? what's wrong? Just go away Spike! go away!
Spike was going back to Twilight's house wondering why Rarity didn't want him at her house anymore, when Spike got home, he told Twilight about what had happened at Rarity's house. Twilight then had to face the fact that it was time to tell Spike the truth. You see Spike, when you grow into a fully grown dragon, you will become an aggressive, killing monster. I'm sorry Spike, but the truth is, when you grow up, I will have to give you up, when Spike heard the words from the purple unicorn he felt that Twilight didn't love him anymore. No! *sniff* no! Spike ran out the door and never came back all day, Twilight had realized that she made a huge mistake.
10 years later Spike came back, he was a fully grown huge rampaging dragon, alarms were going off all over Ponyville as Spike breathed fire at random ponies and destroyed houses, Spike ripped off the roof of Twilight's house and grabbed Twilight from inside the house. Spike!!? why are you doing this to us!!? YOU AND RARITY DON'T LOVE ME ANYMORE!!! that's not true!! me, Pinkie Pie, Rainbow Dash, Applejack, Fluttershy and especially Rarity all love you!! and that will never change!!
Spike was about eat Twilight's head off, but then Spike's expression turned from angry to the feeling of being loved again, the realization finally fell into Spike's angry heart, He gently put Twilight back on the ground and said, I love you to Twilight.
Twilight then gave Spike's huge fully grown dragon head a big hug.
A love spell began to pure from Twilight's horn, Spike then proceeded to help fix Ponyville. Twilight went back to her house and took a letter. "Dear Princess Celestia, for the past 10 years I have learned that some ponies or baby dragons can't always stay the same, everypony Equestria has to grow up some time even most faithful assistent Spike. Your faithful student, Twilight Sparkle" Spike then came back with kisses all over his face, Twilight giggled at the site of the kisses on Spike's face. Spike can you send my letter? sure Twilight, Spike then porceeded to blow the letter Princess Celestia.
That night, Spike and Twilight went out of the town to gaze at the stars. Twilight? yes Spike? I just don't how that love spell from your horn turned me back into the normal me. How did it happen so easily? Twilight had a worried look on her face, well Spike, the thing the caused the spell to work was because truly love you Spike, with the magic I had from our friendship with all the other ponies, I was able to save you from growing even bigger, what Twilight explained to Spike made him worried, tears started to run down Spike's cheeks, Twilight lifted up Spike's face up towards her, look up at me Spike, I love you no matter what, and don't you let anypony tell you differently
the end
One night in Ponyville, Twilight was at home reading some books when Spike came running down the stairs crying, what's the matter Spike? Twilight asked worried, *sniff* I-I just read this book about dragons *sniff* and it said "when dragons grow up, they become more greedy and aggressive and eventually kill ponies" Spike told Twilight crying, Twilight gave Spike a big hug, Don't worry Spike, growing up is not a bad thing, right now you just need to enjoy being you. Twilight said to Spike, this made Spike feel better as he went back up the stairs,
But this made Twilight more worried about Spike reaching puberty and then growing up into a fully grown dragon, what Spike was worried about made Twilight afraid that Spike would kill her in the future, so the next day, Twilight went to Canterlot to get some advice from Princess Celestia, when she got to the palace, she started talking with Princess Celestia. I know dragon just like Spike still grow up, and when they are a fully grown dragon, they turn cruel, greedy, and dangerous, Princess Celestia explained to Twilight, but what will I do when he turns into this monster!? isn't the a spell I use to stop him growing up!? asked Twilight very scared. I am afraid there is nothing you can do to stop Spike from growing up, when your little dragon grows up, either you will have to put Spike down, or he will have to leave Ponyville forever.
Tears started running down Twilight's cheeks, thank you for your time Princess. Twilight left Canterlot feeling scared, helpless and more worried for Spike then ever before, when Twilight got back home to the library, she came through the door sobbing, Spike asked what's wrong Twilight? Twilight used her magic to grab a tissue and wiped the tears off her face. Oh I-I'm fine Spike. Twilight went upstairs and threw herself onto her bed crying for an hour.
