She's the one... Dipper x Reader (Slow Updates)

The Lake

Mabel's Pov
Soon we all arrive at the Gravity Falls lake.
I was wearing a light blue sweater with a beautiful mermaid. A dark green skirt and matching headband.
Dipper wore his usual outfit. Y/n was wearing a (f/c) t-shirt and jean shorts with high top converse. Her eyepatch sat atop her injured right eye.

Just as we arrived, I pulled Dipper aside.
"Dip! Now's your chance to give her the gift!"
"I don't know Mabel, we'll be with Grunkle Stan and Great Uncle Ford all day. Not to mention Soos will be there too. Besides, I want the perfect time to give it to her."
"Don't worry, I'll keep them busy."
He gave me a side smile, "thanks sis."
"No problem brosepth!" (Is that how you spell it?)

We rejoined the others, who were setting up the boat.
I couldn't contain my excitement as I might see Mermando! (Let's just say that he did not get married)
I sent him a glass bottle telling him to meet me here. I hope he does.

Today instead of fishing, we were looking for the floating island head that lived in these waters. Grunkle Ford said he met it by accident before by it trying to eat him. Now he was back with equipment and his trusty apprentice, Dipper.
You could see the determination in their eyes.

Grunkle Stan brought fishing poles to spare the time, but I wouldn't have it.

"Grunkle Stan you can't fish! It might hurt Mermando!"
"What? Who's Mermando?"
"He's my friend that I met awhile ago. He might be here swimming around somewhere! And your hooks could hurt him."
"Mermando?" Grunkle Ford came up. "Sounds like a mermaid, or merman."
Mabel knew that she couldn't hide that kind of stuff from Ford for very long, so she decided to fess up. "Yeah, he is one."
"No way! You met a real merperson? I only found the skeleton of one! You really are something Mabel."
"Thanks Grunkle Ford. You can meet him if you want!"
He smiled. "I would love to! I have a few questions to ask about him and his people."

We were out on the lake searching.
I was keeping my eyes peeled, for any sort of movement from the water that wasn't a fish or someone swimming.

An hour had passed and yet still no sign of him.
Sighing, I blinked my eyes. Dang they were dry! After blinking a few more times, my sight returned to the sloshing water.
'I can't give up hope yet! Maybe he's almost here!' Thinking to myself.
I was so entranced that I jumped when something tapped my shoulder.

"Whoa! Didn't mean to scare ya." Y/n held her hands up in mock surrender.
"You nearly gave me a heart attack!" I responded, lightly pushing her.
"Heheh sorry about that. I was just seeing if you wanted to come scuba diving with us."
"Sure! It'll be much easier for Mermando to find me if I'm in the water!"
"Thats the spirit!" Y/n grinned.
"Oh hey, I've been meaning to ask, if you're wearing the patch, does that mean Bill is possessing you again?" I ask, pointing to her eye.
She hesitated before answering, "Nah, not this time. Its just bruised up and I didn't want to be walking around with a bandage on my head the whole time. Besides, I can pretend I'm Ciel Phantomhive hiding his mark or Mei Misaki hiding her glass, doll eye." (If you get these references I love you!!!)
Mabel decided ignore the fact that she paused and went along with it.

~~Time skip to when they're all in the water~~

No one's Pov
Stan decided to stay above with Soos while Ford, Dipper, Y/n, and Mabel submerged the murky waters below.

'I... don't know... Bill's daughter... why... is wearing... eyepatch? I know... nasty injury.. from.... father but... you can never be.. careful about... trust in.. Aside from Dipper...' Y/n heard Ford's partial thoughts come automatically to her mind, while shining the waterproof flashlight back and forth among the dirty bottom.

A/n: Ok a little side note that I feel like I should point out. Despite demigods, typically half humans and half anything else (ex: demon, witch, magician, etc.) are usually more powerful than if they were a full one. Don't ask me why, but that seems to be the trend among writers. So you were able to read Ford's thoughts with trouble where Bill can't read them at all. Thanks to the metal plate in his head.

We go deeper into the lake until movement catches all of our attention.

"What was that?" Dipper asks.
"It was probably just a fish," Mabel assures him.
Y/n had other ideas.
"I don't think so. I sense power emitting from over there." She swims towards it.
"Wait for us!" We swam after her.
Soon we catch up to her. She was staring intently into inky blackness.
"Y/n?" Mabel waves a hand in front of her face,
"Its here..."
"The face island?" Dipper squinting forward.
As if in reply, a loud roar echoed.
"Everyone swim back to the boat!" Ford ordered.

As you kicked up to give yourself a boost, you felt a tug on your ankle.
