I do not own Gravity Falls.

"Where did you say she was, Pine Tree?" Bill asked again as he followed Dipper up the stairs to the twins' attic bedroom.

"Right in there," the boy answered in an annoyed voice as they reached the doorway, pointing inside the room.

Raising an eyebrow, Bill poked his head in, his uncovered eye widening as he saw what Dipper had described to him earlier. Quickly, he turned back to his companion.

"... I see the issue."

"How couldn't you? She made the thing cover the entire room!"

"And you want me to get her out?"

"That's the idea."

"Why didn't you do it yourself?"

"She kept trying to drag me in by my vest. Maybe she'll listen to you."

"Fine, fine."

Hesitantly, Bill took a step into the room, staring at the large structure Mabel had built.

"Shooting Star?" he called out upon entering. He soon after heard rustling, and saw Mabel's head pop out of her hideaway.

"Hiya, Bill!" she replied happily.

"Mabel, what exactly are you doing?" he asked slowly, bending down to speak closer to her face.

"Hanging out in my blanket fort! Isn't it neat?"

"Wouldn't it be better if you... came out?"

"Pffft, why?"

"... Well, your brother would like access to his bed, for one..."

Mabel scoffed at the point.

"He could have joined my fort, but he's being a grumpy pants, and it looks like he got you in grumpy land too!"

"I'm not in 'grumpy land'!" Bill replied indignantly.

"You're acting like it!" she said with a huff.

"How do I prove to you that I'm not?" he asked swiftly, not noticing Dipper's frantic signaling for him to stop.

"You come in here with me and hang out!"

"Shooting Star, I think our time would be better spent somewhere else-" he had only started speaking, barely finished with his first sentence, when Mabel covered his mouth with her own, effectively stopping his explanation. When she pulled away, he did not continue, causing her to smile brightly.

"Want to come in now?" she asked sweetly.

"Move over, Shooting Star, I'm getting in there."

"No fair! You bribed him!" Dipper yelled from the doorway.

"Sorry, Dipping Sauce, I'm just too lovable!"

"You were supposed to be helping me, Bill!"

"You don't provide kisses, Pine Tree."

"YOU BOTH SUCK!"

I will never stop writing fluffy Mabill. Neeeeevvver.
