Dipper and Mabel both smiled as they walked into the door at the Mystery Shack. They haven't been at Gravity Falls since they were twelve, now, they were very excited to be back again.
The twins walked inside of the shack with Wendy and Soos hugging them both.
"Oh my gosh, dudes, I missed you so much!" Soos squealed as he squeezed Dipper and Mabel. "We did... Too..." Dipper replied, trying to get out of Soos's grasp. Wendy then came up to both of them and hugged each. "Glad to have you dorks back," Wendy said, smiling. "Hasn't been any fun since you two left."
The twins both smiled as their Grunkle Stan and their Grandpa Stanley came into the Gift Shop. "Hey, haven't seen you two in years!" Stan said, hugging them. Stanley looked at them, "wow, you guys sure have grown since I last saw you."
And they did. Dipper was more taller, more broad shoulders with a muscular body type. He still wore an orange shirt, blue vest, and the Pine Tree hat.
Mabel grew tall as well. She had more of a womanly figure now along with her hair being so long it barely touched the floor along with her braces off. She still wore sweaters and kept the same optimistic attitude but toned down a bit of her silliness.
It was when a blonde haired teen came in the Gift Shop when Dipper and Mabel recognized her.
"Pacifica?" They both said. The blonde smiled and nodded.
Pacifica was once on Dipper and Mabel's bad side but when they started being around her more and understanding her more, she befriended them. She went to Mabel's sleepovers and hung out with the twins back when they were twelve.
Dipper blushed as he examined Pacifica. She had a more womanly figure with slightly more curves than Mabel, long blonde hair that goes a little farther than her waist with bangs, and the same beautiful blue eyes.
"Oh my gosh, it's been forever since I last saw you two!" She gave them both a big hug.
After the twins hugged and chatted to their old family and friends, Mabel and Dipper went up to their rooms in the attic to finish unpacking their things. "So Dipper," Mabel turned to her brother with a devious smirk on her face as she was putting her sweaters in the closet. "You're over Wendy, aren't you?"
Dipper sighed. "Mabel, we all know that she just thinks as me as a little brother or something. Besides, what made you ask that?"
"Oh, nothing," Mabel continued, "I just saw you blushing at Pacifica today..." Dipper glared at his sister, "hey, I do not have a crush on her! I was just surprised to see her, that's all."
"Yeaaaah." Mabel said sarcastically as her brother rolled his eyes. "Well at least you have girls following you like a puppy." Mabel said with a tone of jealousy in her voice.
Mabel was right. Since Dipper had reached puberty, all of the girls at their school had been drooling all over him. Even while he was going to the bus to Gravity Falls, four of the girls from his neighborhood got him hugs and 'will you go out with me?' cards but he declined all of them as 'sorry, but I'm just not interested in a girlfriend right now.'
As for Mabel, guys were talking about how hot she has gotten over highschool but once they actually talk to her and know her crazy personality, they turn and run. That's why Mabel hasn't gotten a boyfriend the past three years.
Dipper could sense something wrong with his sister. "Mabel, please don't tell me you're still upset about the whole 'summer romance' thing, aren't you?" He said as he placed his hand on her shoulder. "Yes, I mean, I just wish someone would give me a chance, that's all..." Mabel muttered sadly, looking down.
"What about that Armando guy you met when we were twelve?" Dipper asked. "Doesn't he count?"
Mabel chuckled, "it's Mermando and he was one of the only guys who liked me in that way, he even gave me my first kiss..." Mabel said as she dreamily thought of the merman that she had met in the Gravity Falls pool and helped him to escape and gotten her very first kiss. Her dreams ended with another memory.
"But he's married to the Queen of the manatees to stop a civil war. He couldn't be with me..." Mabel hung her head and sighed.
"But you know what? I'm just going to stay positive! Who knows, maybe I'll get a boyfriend this summer!"
"That's the spirit, Mabel." Dipper smiled, happy that his sister was back to her bubbly happy self. She then was at the door, "I'm just going to go to the lake for awhile. I'll be back soon."
"Okay," Dipper then hugged his sister goodbye. "Me and Pacifica are going to the ice cream shop downtown. See you soon!"
"Bye, Dippingsauce!" Mabel said as they both walked out of the gift shop door.
But what the didn't notice was a triangular shape hiding beneath the walls, watching their every move.
"Yes, Pine tree and Shooting star, see you soon..."
