"Is it hot in here? It's awfully hot in here," Dipper wiped the sweat beading on his forehead. "Mabel, could you open the window?" He stood at the window straightening his bow tie for the fourth solid minute.
"It's already open, Dipper, and the only thing hot in here," Mabel smiled from ear to ear, she was laying on her stomach on the bed, "is you for Candy!" She buried her face into the pillow and squealed a girlish squeal while kicking her legs.
Dipper blushed, "Stop it."
"Stop what?" Mabel asked teasingly.
"That thing."
"What thing?" Mabel rested her cheeks on her hands.
Ever since she'd set the two up on her 'Magical Mystery Tour' ploy out in the woods she'd been reminding Dipper of his relationship status every chance she could get. Dipper's cheeks turned red every time she brought it up. "Anyway, just don't embarrass me on purpose tonight, okay?"
Mabel gasped in fake shock. "I'm sure I have no idea what you're talking about."
"Yes, you do," Dipper opened up a little tin of hair gel and slicked back his hair as best he could. "Because you do it all the time, especially in front of..." Here we go, thought Dipper.
"In front of girls you like?" Mabel's smile somehow got bigger. Dipper turned back to the mirror with a 'harumph' and worked his hair as best he could into a semblance of order. "Listen bro, I'm the one who set up the Magical Tour thingy and I'm the one who set up this up tonight. Plus, Candy's my BFF..."
"You've known her for how long?" said Dipper.
"Ugh, long enough for her to be my BFF!" she frowned.
"Just don't be weird tonight," Dipper tried to smooth out his hair with a comb.
"Fine! I promise not to be weird," Mabel hugged her pillow, she smiled again, "as long as you promise that I can be as weird as I like at your wedding reception!"
"Mabel!" Dipper's cheeks, on cue, turned fire hydrant red. He tried to ignore her.
"And then you'll have little half-Dipper half-Candy babies!" Mabel started jumping on the bed, "And they'll be twins! And I can be their Auntie! And you two will name your baby girl 'Sun' but we'll call her 'Sunny' and the boy can be called 'Jerome' and..."
"Tyrone..." whispered Dipper.
"What was that?"
"Uh, uhm, don't you have something you need to be doing?" Dipper started sweating and hoped she didn't notice.
She didn't. "Oh Em Gee, you're right! I still have to put the bread-sticks in the oven!" She vaulted off the bed and out of the room."
"Well that was a freebie," said Dipper to the mirror.
She ran back in and gave Dipper a quick hug, "I promise not to embarrass you tonight." She ran out again.
"Thanks, Mabel." He smiled and went back to fiddling with his bow-tie.
