Dipper's POV:

I watched helplessly as Mabel ran out of the room, crying. What have I done? I pushed Pacifica off of me, but before I could run after Mabel, Pacifica grabbed my wrist.

"What's the hurry?" She asked, as if nothing had happened.

"I-I need to make sure she's okay." I tried to break away from her, but it only tightened her grip.

"Pfft. She's fine." She pulled me closer and smiled. "Besides, now no one will bother us." She leaned in for another kiss, but I pushed her away.

"Leave me alone." I said firmly before running out the door.

I ran down the stairs and tried to look for Mabel. I looked all over the place. I asked everyone I could think of. She was nowhere to be found.

I went to the front of the house. Nope. I was really starting to worry. How could she disappear in thin air like that? I shook my head. It wasn't possible. Where could she go?

"Dipper!"

I turned and saw Wendy, walking around to the front, stumbling a bit.

"Did you see-" She stopped for a second. "Did you see who stole my truck?"

"Wait, what?" I looked at the now-vacant spot where her truck used to be. I shook my head. I didn't have time for this. I had to find-

Then it hit me.

Mabel must have taken the truck.

Now I was REALLY worried. She didn't know how to drive. What if she got in an accident? What if the police caught her?

"I'll take that as a- as a no." Wendy started walking back.

"Wait!" I yelled. She stopped and turned back. "Yeah?"

"You have any money for cab fare?"

Mabel's POV:

"...so that's what happened. What do you think, Dr. Waddles?" I finished as I looked up at him. He didn't say anything (of course), he just kept chewing on the notepad I gave him.

I let out a sigh. "Well, thanks for trying." I said. I kissed Waddles' forehead before walking away to my room.

I shut the door and threw myself on my bed. I still couldn't believe I acted like a child when I saw Dipper and Pacifica kissing. Maybe it was because I thought Dipper and I could be together. That we could become something more than twins. The fact that I didn't just like him, I loved him.

I shook my head. I'd been living a fantasy this whole time. Seeing what I wanted to see. There was no way Dipper wanted what I wanted. He loved me, but as a brother, as a sibling, as a best friend, as a twin.

I felt a tear escape my eyes and roll down my cheek. I couldn't help it. I just wish Dipper would fall in love with me.

(Time Skip: 1:49 AM)

Knock, knock, knock

I must've fallen asleep, because I opened my eyes and sat up in my bed. Who could be at the shack at this time of night? Tourists? Jeez, I hope not.

Then I heard the jingle of keys. The door slowly creaking open. Footsteps stomping down the hall. I tried to stay calm.

"Mabel?" I heard Dipper's unmistakable voice. I let out a sigh of relief. At least it was someone I knew and not a robber or something. Then again, what was Dipper doing here?

I lied back down on my bed, facing away from the bedroom door, and pulled my blankets over me, pretending to be asleep. Hoping that he wouldn't come in.

Dipper's POV:

"Mabel?" I called her name for the second time. Still no response. That's when I saw Mabel's door wide open.

I was really confused. She NEVER left it open. Ever. I knocked on the door. "Mabel, you in here?" I asked, even though I knew she wouldn't answer.

Even though the room was dark, I could still see her lying in her bed, facing the other way. I walked over to the side of her bed, no hesitation this time.

"Mabel?" No answer. I came to the conclusion she was asleep and was about to leave when something caught my eye.

Her fingers were moving under the covers. I smiled. She's faking. I knew it! I turned back towards her and shook her, but not too hard.

She slowly moved up. "Dipper!" She groaned. "Why did you wake me up?"

"Because you were already awake."

She turned to me and smiled. "How'd you know?"

I smiled back. "I'm your twin. You can't put anything past me." My smile faded. "So... why did steal Wendy's truck."

Her smiled faded as well and she let out a sigh. "I-I don't know." She began to twirl her hair again. Wow, she's done that a lot lately. "It's just- when I saw you two kissing, I guess I was, kind of, you know..." She took a deep breath. "Jealous." She looked away from me as she finished.

"You were?" I asked before remembering her feelings for me. I knew what it was like to love someone, but always have an enemy in the way.

Mabel turned back to me. "Listen, Dip, I'm sorry that I was being a baby about this. I should've been happy for you two."

I saw her starting to cry. "No, Mabel. It's okay."

She was obviously surprised. "Huh?"

I tried my best to explain. "Listen, I have no clue why I kissed Pacifica. I dunno, it just happened. And you saved me from that, Mabel."

"Oh, wait a minute. You don't like Pacifica?" Now she was intrigued.

I shook my head. "I mean, she's a lot more fun that she used to be, and I think I actually like her as a friend, but I don't LOVE her." I looked down. "Besides, I'm in love with someone else."

I never meant to say that last sentence. Suddenly I saw that goofy grin that I knew so well forming on her face.

"Really? Who?" Yep, that was Mabel for you. Always wanted to know.

I didn't answer. I was trying to come up with another person, but my mind went blank. Dammit, brain! Now is NOT the time.

Mabel grabbed my shirt and shook me violently. "Tell me! I gotta know." She whined.

And that's when I decided. No more lying. I HAVE to get this off my chest now!

I took a deep breath. I tried speaking, but words wouldn't come out. I was scared to say it. But I had to.

Mabel was getting impatient. "C'mon, bro bro. You can tell me anything." She said in her cutest voice possible. She's not helping. Oh well. C'mon, Dipper, enough of this. Just SAY it.

"It-it's you." I choked out.

Mabel's POV:

"Wha?" was all I could get out. I couldn't believe it. Did he just say that or am I going crazy?

"You. I'm in love with you." He repeated, much better speaking that the first time.

"B-b-but I thought..." I didn't need to say any more.

Dipper nodded. "Mabel, I was so stupid, for so long. It had to be you. You are the most awesome and most beautiful girl I had ever met. No one could compare to you, in my opinion. Mabel, I-I love you."

"I-" My mind was officially blown. I couldn't find the right words. "Dipper, I don't know what to say."

Dipper smiled. "Then don't say anything." Suddenly, we felt the urge to lean in and kiss each other. And that's exactly what we did.

Kissing him was even better the second time, now that I knew he loved me. Eventually (and I do mean eventually) we broke the kiss, but this time he didn't run away.

I only had one question left to ask.

"So... are we together now or what?" I asked.

Dipper smiled. "I'd be honored."

I squealed as I jumped into his arms and pulled him into another kiss. Then another. And another.

Between kisses, Dipper stopped me.

I frowned. "What's wrong, Dippingsauce?"

"Nothing. It was just... what would happen if someone found out?"

I bit my lip. I hadn't thought of that. "What are we gonna do?" I panicked.

Dipper scratched his chin as he thought. "Listen to me, Mabel. We can't tell anyone about us. Not Grunkle Stan, not Soos, not even Wendy. We can't take the risk of someone finding out. You got it?"

I hesitated. Would I actually be able to lie? I almost never lied and when I did, it wasn't very convincing. I slowly nodded.

Dipper smiled. "Good. Now, where were we?"
