Dipper's POV:

I felt the bus come to a stop and I slowly started to open my eyes.

Mabel was sleeping on my shoulder and I gave her a slight nudge.

"Psst, Mabel!" I whispered, "We're here!"

"hmm?" she responded, rubbing her eyes.

We both looked out the window and saw our parents at the bus stop waving with "Welcome Home!" signs.

"Wow, I can't believe summer happened just like that!" Mabel said as we started getting our things.

"Yeah, I know! But now we can tell Mom and Dad about all the awesome stuff that happened!" I added.

Mabel nodded her head in agreement and the bus driver opened the door.

We ran towards our parents and they greet us with 'welcome home' hugs.

"Mom! Dad! We had sooo much fun at Gravity Falls! Can we go again next summer?! PLEASE!!!" Mabel exclaimed as she jumped up and down.

"Sweetie, calm down! You just got back!" Mom answered as she stopped Mabel from bouncing and gave her a small kiss on the forehead.

Waddles then came out of the bus and waddled over to Mabel. He looked at Mom and Dad with his head tilted like a confused puppy.

"Uhhh, who's this?" Mom asked, pointing at Waddles.

"He's my pet pig!" Mabel answered as she picked him up and gave him a big hug.

Mom gave a nervous chuckle and helped Mabel with her stuff.

I laughed at Mom's reaction when Dad starts heading towards me.

"Hey Champ! I like your new hat!" Dad said as he took it off my head and ruffled my hair, "You need any help with your bags?"

"Nah, I got it covered it Dad. I got a lot stronger during the summer you know?" I answered while I start loading the car.

"Pffft. Dipper? Strong? I don't think those two worlds could ever be used in the same sentence!" Mabel laughed as she put Waddles in the middle seat and gets in.

"Mabel, I literally saved you from a nine year old psychopath and went face-to-face with Bill! And after that you still can't say that I'm at least a little bit stronger?" I asked/laughed while getting in and putting on my seatbelt.

"Bill? Who's Bill?" Mom asks as she gets into the car.

"Oh, it's a looong story." I chuckled.

"Well you can tell us all about it when we get home! For now let's just listen to some tunes!" Dad said as he got into the car and turned on the radio.

I smiled and started tapping my foot to the song.

We started driving home and Mabel stared at me with a confused look.

"What?" I asked with a confused look.

She leaned towards me, behind Waddles, and whispered into my ear a question that leaves me dumbfounded, "Who's Bill?"

===============================

After the drive home, we dropped our bags off in our room and met together at the dining room table.

Mom put some fruit and crackers in the center of the table and we all sat down to chat about what we did at Gravity Falls.

"There's so much I want to talk about! Uh, where should I start!" I asked excitedly.

"Calm down Dipper, you're starting to sound more like your sister!" Dad chuckled as he took a bite of an apple.

"Why don't you start on the first day that something interesting happened?" Mom asked.

I started snickering at the reminder of Mabel's first boyfriend.

"What's so funny?" Mom and Dad asked at the same time.

I looked at Mabel with a smirk on my face, "Nor~man." I sang at her jokingly.

Mabel rolled her eyes, annoyed.

"Who's Norman?" Mom asked.

"My first boyfriend." Mabel sighed, "He wasn't really my type though."

I started laughing harder, "Not your type?! He was literally a stack of gnomes Mabel!"

My parents looked at each other in confusion.

"Dipper," Mabel looked at me angrily, "What are you talking about? He was just a little edgy and I wanted someone more outgoing."

"But Mabel-" she cut me off.

She lifted up my bangs and put her hand on my forehead, "Are you feeling ok Dipper?"

"Yeah..." I answered suspiciously while removing her hand from my forehead, "Are you?"

She gave me a strange look and nodded slowly.

Mabel stood up and cleared her throat, "It's getting a little dark already and I want to start unpacking. Can we talk tomorrow?" she announced.

"Of course Sweetie, I'm sure you had a long trip back. Dipper why don't you join your sister?"

"But I have so much to talk abou-" Mabel grabbed my hand and dragged me to our room.

She slammed the door and gave me a cold hard stare.

"What?" I asked.

"What? WHAT?!" Mabel yelled angrily, "You just called my first boyfriend a stack of gnomes! You said a crazed maniac was after me for half the summer! And then there's this 'Bill' guy!"

"Mabel!" I answered back, "How can you not remember?! Don't you remember all those paranormal creatures we saw and how Gideon tried to steal your heart AND the Mystery Shack?"

"Gideon was no maniac Dipper! Sure, he REALLY liked me, but he accepted that I just wanted to be friends and that's it!"

"But what about Weirdmageddon and Bill?!" I asked.

"WHO THE HECK IS BILL!" Mabel yelled.

I step back slowly in fear, "Mabel there's something wrong! I think Bill did this! We need to talk to Ford!"

"Dipper, there IS something wrong! It's you! You sound like a crazy person!"

Mabel sighed and calmed down, "I think you just need some rest."

"How can I sleep Mabel?! Bill did something to you and we need to fix it!" I yelled back.

Mabel started pushing me to my bed but I wouldn't budge.

"NO! He did something to you! I know it!" I continued protesting.

Mabel gave in and stoped trying to push me, "Alright then, I believe you. Tell me everything that happened this summer."

I smiled and we sat down on the floor.

I told her about everything, starting from me finding the journal, to us stopping Bill and Weirdmageddon.

"This sounds serious!" Mabel said once I finished.

"It is! I think Bill might've done something to make you forget!"

"Well, I think we should first get some sleep bro-bro, it's been a long day."

"No! We can't sleep now! We need to call Grunkle Ford!" I said without any hesitation.

"Fine, let me just go downstairs and get you some water first."

"Thanks Mabel. And thanks for believing me." I said while getting up.

"Anytime Dippingsauce!" Mabel said as she left the room.

How did this happen?! We defeated Bill and everything went back to normal!

I started pacing around the room and continued to ask myself questions on how this could've happened.

Mabel then came in with a glass of water and handed it to me.

"Thanks." I said, "And what took you so long?"

"Ohhh, Mom had a few questions about Gravity Falls and how our birthday went."

I nodded and took a sip of the water, "Ew, what is this? Are you sure you got water Mabel?"

I suddenly started to feel light headed and dizzy, "And why do I feel so tried all of a sudden?" I asked while yawning.

"Look Dipper, I'm really worried about you. It was for the best!" Mabel answered nervously as she fiddled with her fingers.

The realization of what Mabel did then sunk in, "Mabel I thought you believed me! I'm telling you, I'm NOT crazy!"

I then fell backwards onto my bed, "I'm not- I'm not crazy Mabel.."

And then all I saw was darkness.
