Previously...

Will smiled, "Okay... so... I'm assuming your dream date would be romantic as h***?

"Yes. A candlelight dinner, roses on the floor, steak and vegetables, and wine on a hill, watching the sunset," Mabel sighed.

Will snickered, making a mental note about her dream date for later, "That sounds wonderful."

"Yeah, it is..." Mabel looked down.

A few hours later...

Mabel walked into her room for some more yarn to make a sweater with, when she noticed a sparkly pink envelope on her bed, with a bowl of sparkles next to it. She gasped, picking up the envelope, and opening it.

She read the letter aloud.

Dear Mabel,

I have always wondered about you. How you stayed enthusiastic throughout the problems of life. How everything magical seemed to go over to both of you, like you and Dipper are magnets. Yet, you've really helped me with my problems, which I have a lot of, even you never realized it. If anything, everything seems to go wrong for me. Both for me, and the only family I have left. Even though, they still stay positive, and... it's a little annoying. They'd always tell me everything, until... I left for a few years. Yet, once I returned, I met you and Dipper. You were so nice to me, it was amazing. I was terrified of you, but... I liked you. Your positivity was unbelievable. It fascinated me to no end. You're still nice to me, and you were careful with what you said when they told you what I'd been through. I was grateful for it. So... what I wanted to tell you, is that you're beautiful and... I love you. I'll... make you a dress and leave it in your room in an hour. I'll pick you up for your dream date thirty minutes afterwards. I hope you'll be happy about knowing this. Oh, and... by the way... the bowl of sparkles has two rings in it. It's... important. I'll explain on the date, so you should take them.

Love,

Your Secret Admirer.

She squealed, running to Dipper's room, after taking out the rings, putting them in her pocket, "Dipper! DIPPER! Someone asked me out!"

"What? Someone asked you out? Why?" Dipper asked, sitting on his bed.

She grinned, "I don't know, but it's amazing, and I can't wait, and... and... yes! I finally get my dream date!"

"Do you know who it is?" Dipper asked.

She giggled, "No! It just says that they're my secret admirer!"

"Hmmm... can I see the letter?" Dipper asked.

She smiled, "Sure. Let's see what you make of it."

"Hmm... Well, they seem to really admire you. They have an older sibling, as they really care a lot about your admirer. I wonder what the rings do," Dipper mumbled.

She nodded, "Yeah, I'm curious as to what the rings will do. I'm sure I'll find out in an hour and thirty minutes."

An hour later...

Mabel looked at the sparkly pink dress, made out of purely sprinkles and sparkles, gasping, "How did someone make this?"

It took her around 25 minutes to figure out how to fit in the dress, and by that time, Dipper was banging on the door, telling her that she had five minutes before her date.

Mabel opened the door, the dress surprising Dipper, as he spoke, "Wow, sis. Whoever you admirer is, they must know a lot about you... which is a little scary. They also might as well be rich. I bet there's about a million or so sprinkles and sparkles on the dress."

"It's amazing, isn't it? ...and this is only our first date! I wonder what else they'll give me!" Mabel grinned, twirling around in the dress, for Dipper to see.

Dipper sighed, "You have a few seconds."

"I know," Mabel smiled.

Dipper gulped, "Mabel... there's someone behind you."

Mabel turned around, smiling, "Hi! Are you my secret admirer?"

"Yes, that's me. I hope you like the dress," They looked down at the floor.

Mabel nodded, twirling around in it, "I love it!"

"You do look wonderful in it, Mabel," They admitted, watching her twirl.

Mabel grinned, "Thank you so much!"

"I'm assuming you have the rings?" They asked.

Mabel nodded, "Yeah, I have them."

"Good. We'll need them." They sighed, "We need to get going."

Mabel nodded, taking their hand, as they walked away. They walked for a while, before getting to a hill. On the hill, was a table with wine, steak, vegetables, and a candle. She gasped, sitting down on the left side of the table, making them sit on the other side. They both ate in quiet, until Mabel couldn't take it anymore.

"What's your name?" She blurted out.

They held up their finger, signaling for her to wait for them to finish eating, before they looked down, "I knew you were going to ask that first. I'm not tell you... yet. You'll find out by the end of this. You can call me Blue for now."

"Aww... why can't I just call you mine?" She asked.

They laughed, "That works too."

"Okay... Blue... so, what's your favorite color?" She asked, curiously.

Blue sighed, "Blue, obviously. You?"

"Pink, but I think you know that," She giggled.

Blue snickered, "Yeah, I know that. I don't think you mind that I know a lot about you."

"No, I don't. I've already dealt with others knowing a lot about me," She smiled.

Blue adjusted their mask, letting her see their mouth, they smiled, "I bet. In a place like this... that's bound to happen. You want to say something, but your holding back. What is it? You can tell me. I won't tell."

"Well... there's this guy I like, but... my brother's dating his brother, so... I don't know. Because of it, I don't think it'd be right," She looked down.

Blue laughed, "Hey, look at me. It's alright. I'm having the same problem. Although, it's a girl I like."

"... Hey, Uh... I think I want to go... it was nice to see you, though... could you at least tell me your name?" She asked, getting up, after she was finished.

Blue frowned, "Sit down, Mabel. There's only last thing I want to do."

"... I don't like the sound of that," She admitted.

Blue nodded, "I know. It's important, though..."

"Why?" She asked.

Blue looked down, "Well... I'm... not exactly human, which is kind of why I'm hiding my face... I don't want to scare you, or freak you out, so... I put a mask over my face. So... Incase you... die... I'm having you wear the ring, so that... I'll be able to find you... in your next life... and you'll be guaranteed many more future lives... but, of course, not in the same form, and you won't remember anything from your past lives... but I'll know. I'll know when you've been brought back. My older brother's already done it many generations ago with his soulmate, and... I'm doing it with mine right now."

"So... I'm your soulmate?" She gasped, "You're not human? What are you?"

Blue sighed, "Yes... you are. I'm sure of it. No, I'm not... but you already know this about me. You already know this, too..."

"Fine. I'll... put it on. So... can you tell me your name after I put the ring on?" She asked.

Blue nodded, "Of course."

"Okay..." She put the ring on, examining it, "It's pretty... so, who are you?"

Blue took his mask off, before looking up at her, frowning, "I'm sorry, Mabel..."

"Will? What? Why are you...? Oh. Ohhhh." She gulped.

Will sighed, shaking his head, causing his short hair to go in his face, "Yes, it's me... it's been me this entire time... and I'm still sorry."

"Wait... How'd you make this dress, then?" She asked, confused.

Will smiled. "Magic," He snickered, letting little bits of yellow balls of light move in his hand.

She gasped, "Wow. That's... amazing. ... why are you sorry?"

"... because... if the Gleeful's find out about... us... then they'll go after you, to get revenge on me escaping. That's probably part of why they took Bill..." Will explained, biting his lip.

She frowned, "Would teaching me magic do anything to help?"

"... Maybe. They don't have their mystical amulets, so... they don't have any of their own magic... not that mystical amulets gave did much... so, maybe..." He admitted, "We can start tomorrow. Near noon. You can bring Dipper along, too... and Ford. Ford probably knows a bit, from him, but... I'm not sure."

She nodded, getting up, "Okay..."

"Oh, and Mabel? There's... another thing," He looked down, getting up, walking over to her.

She frowned, "What now?"

"I love you," He admitted, before kissing her during sundown.
