Do's and Don't's of the holidays.
Meet them under the mistletoe.
Christmas was coming, and Mabel was in her normal holiday craze. She had broke out the mistletoe, and the matching Christmas sweaters that Mabel knitted for her, and Dipper. Dipper hated that sweater, but often wore it to make Mabel happy.
One morning Mabel decided that she was going to tuck a stem of mistletoe in her headband, and test how irresistible she was. Dipper just shook his head, and put on his sweater that matched the one Mabel had put on already. He thought she had left the attic, but after he pulled the sweater over his head; Mabel was there flipping the switch on the small battery pack in his sweater. The small blinking lights in his sweater began to blink in shades of red, green, blue, and yellow. Mabel smiled showing off her braces, before she left the room, her matching lights shed light down the steps as she moved.
It wasn't surprising that Grunkle Stan had posted mistletoe in different locations in the Shack. It was both a device to embarrass people, but also a way to bring some Christmas spirit to the Mystery Shack. It was not a surprise that Lil' Gideon had came to the Shack to talk to Mabel with a stem of mistletoe pinned to his suit jacket.
"Gideon," Mabel commented as the feeling of unease filled the Shack. Dipper wanted to glare at Gideon for being at the Shack in the first place, but stopped himself.
"Mabel, sees something in him," Dipper thought inwardly with a curt expression painted on his face.
Mabel walked over to Gideon who stood in the doorway. Under the mistletoe. Unconsciously they stood under door frame together. Grunkle Stan laughed.
"Now, if only I could get Dipper, and Wendy under mistletoe," Stan commented.
Gideon blushed realizing that he was not under one, but two sprigs of mistletoe. Mabel smirked, before leaning in to say something. "You owe me two kisses," Mabel muttered.
"Of course my Queen," Gideon said endearingly. He leaned in to kiss Mabel.
"One," Mabel counted the mistletoe fell from between her green headband, and her curly brown hair.
"Two," Gideon muttered as he looked into her eyes. He realized that they both had mistletoe on their person. "Three." He gave her a third kiss to account for his mistletoe.
Gideon walked away with three kisses, a sprig of mistletoe, and the glow of Mabel lit up sweater in his mind.
