Many days went by, and the princesses still trying to figure out how to get Flash Sentry and Twilight was still thinking about Leo and how he save her life and wonder if she ever sees him again.

Meanwhile back at the Demon World in the Castle, Leo was looking at his Crystal Ball and saw a happy couple walking and smiling at each other then he heard the doors open and he make his Crystal Ball disappeared and coming in is his siblings and friends.

"Leo we need to talk." Said Raph and Leo was waiting for Raph to speak." One of the demons spy on the three princesses and they were trying to figure out how to get the guy we took to the dungeon and we think that they might bring an army."

When Leo heard it he had an idea and then he smirk evilly then when his siblings and friends saw his smirk they were about to say something till Leo interrupted them.

"Raph, you said that the princesses want that Flash guy back right?" Said Leo still smirking." Well send a message to them they will have him back, but we're going to make a trade."

Meanwhile at the castle the princesses were still coming up with a plan till a royal guard came to them saying to the princesses that a letter just came. So when Princess Celestia open the letter she gasp and her sister wants to know what's wrong so she reads it out loud.

Dear Princess Celestia,
I heard that you want Flash Sentry back in one peace, and I noticed that you been trying to come up with something. So let me offer you a trade I will decide to give you Flash Sentry and make sure he's not hurt, but in return I want a BRIDE! Meet me at the cave with my bride at midnight or Flash Sentry will die.
Sincerely:
Leonardo the Demon King.

After that the princesses gasp and discuss about it. But what they don't know is that the mane 7 was outside listening everything and they gasp.

"I don't believe it!" Said Rarity." Leonardo, the demon king wants a bride but he never falls in love!"

"I know right." Said Rainbow Dash." But he said he will give us back Flash Sentry if we give him a bride."

"But why will the princesses want Flash Sentry back I mean he betray us." Said Pinkie Pie.

But before any of the girls continue they realize that Sunset and Twilight isn't nowhere to be seen them the princesses came out to explain to the girls till they realize they heard everything and that Twilight and Sunset are no where to be seen.

"Where is Twilight and Sunset?" Asked Princess Celestia.

But before any of them can answer Sunset Shimmer came with tears. So the the girls ask her what's wrong.

"Sunset Shimmer what's wrong?" Asked Princess Celestia." Where's Twilight?"

"She told me not to tell you, I made a pinkie promise to her." Said Sunset with tears.

"What do you mean, where's my sister?" Asked Princess Cadence.

Meanwhile Twilight was heading to the cave where Leo is wait. A few minutes ago after they heard Princess Celestia reading the letter, Twilight takes Sunset private to talk. She says to Sunset that she will be Leo's bride, but when Sunset was about to refuse, Twilight said that he save her so it's probably a good idea to repay him. So when Twilight was about to go she told Sunset to promise not to tell anyone or follow her, so when Sunset promise they hugged each other and Twilight went to the Cave where Leo is waiting.

"Hello?" Said Twilight as she look at the cave to see if anyone is there." Okay Twilight you can do this, you just gotta be brave. Hello? Leo?"

"Well well well." Said Leo as he appeared in front of Twilight and she gasp in horror." If it isn't the Element of Magic, I'm surprised to see you here. If your sent here by Princess Celestia to reason me, tell her that my mind hasn't changed I will take a bride and nothing else."

"And a bride you shall have!" Said Twilight being brave.

"Oh well, tell me who is the lucky girl?" Said Leo.

"Right here." Said Twilight." I will be your bride."

"Ha ha ha, this a joke right your sent by Princess Celestia, Princess Luna, that Princess Cadence right?" Said Leo and he saw that Twilight wasn't joking." You're serious, you want to be my bride and nobody put you up to this?"

"This was my choice, but if you rather have someone else, I completely understand that I'm not the most attractive-" but before can continue and was about to walk Leo got in front of her interrupted her.

"Oh no no no, I didn't say that I wasn't attracted to you." Said Leo. Then he look at Twilight and touch her soft hair and realize that she is beautiful." Well you'll do, but tell me my dear, are you sure you want to this, because if you do there's no turning back!"

"If I marry you, will you keep your promise to free Flash Sentry?" Asked Twilight.

"My dear, you had my word and I will give you anything you want, you see I want my bride to be to be happy." Said Leo." Maybe I should be romantic. Let see, you prefer a diamond my dear?"

Then Leo snap his fingers and appeared at his hand is a box with a ring.

"So my dear, will you marry-" but before Leo can continue a voice call Twilight and they look and seeing Shining Armor, the princesses, and her friends trying to get to her till Leo put a force so they wouldn't get closer.

"Do you all mind, I'm in the midwife a proposal here!" Growled Leo.

"Wait please, let me say goodbye to my family and friends please." Said Twilight. Then Leo made the forcefeild disappear to let Twilight say goodbye.

"Twilight what are you doing, you don't have to do this!" Said Shining Armor.

"I had to so Leo can free Flash Sentry even though he betray us, please this is my choice." Said Twilight, then Shining Armor hugged her.

"I'll miss you Twilight." Said Shining Armor with tears in his eyes.

"I'll miss you too Shining Armor." Said Twilight as she hug him back and so Twilight went to her friends and they hug her.

"Will miss you Twilight." Said the girls.

"And I'll miss you girls too, promise me that you will keep fixing a friendship problem." Said Twilight and the girls promise and then Twilight went to the princesses and they hugged her.

"Oh Twilight your the best sister I ever had please be okay." Said Princess Cadence.

"Oh Twilight, your like a daughter to me, please be okay." Said Princess Celestia with tears in her eyes.

"I will and promise me to keep Canterlot safe." Said Twilight and the three princesses promise and so Twilight went back to Leo who is still waiting for an answer.

"Well my dear what's your answer?" Asked Leo.

"I will marry you Leo." Said Twilight as she took the ring and put it on her finger.

Then Leo snap his fingers and he and Twilight disappear and Flash Sentry reappear then Shining Armor grab him and he and everyone else were hoping that Twilight will be okay.

Meanwhile Twilight and Leo had both arrived at the Demon World and Twilight is shock because she's the first person to ever see the Demon World.

"Well my dear here we are your new castle like what I done?" Said Leo as Twilight look at the castle."
