Mabel dealt with the news well, at first. Dipper’s shaken and apologetic expression informed her that something very-not-good was in his clenched fist. Even then, when he revealed the wet, misshappen and smeared paper journal, she could feel the back of her throat clench as her vision suddenly blurred around the edges.
It wasn’t like the journal itself was hard to make, and she had whipped it up in just a few hours when she’d been crafting it for him, but seeing it ruined and pulped was like losing a part of their memories in Gravity Falls. That little journal hadn’t seen the outside of the trunks for years, but the real journal…Oh man, that was the one that started it all. All the good, all the bad, and probably quite a bit of what happened in between, and the representation of those unforgettable moments was sitting soggy and forlorn in Dipper’s palm.
She took a shaky breath, willing the tears down, but every instinct was pushing her to find a quiet corner to sit down in and hide in Sweatertown. Dipper pulled her into a hug, murmuring “Oh god, I’m sorry Mabes, I’m sorry. I totally fucking forgot I had it in there when we went through the slide. I’m-I’m…sorry, Mabel. I’m sorry.”
He repeated that over and over, kissing her forehead repeatedly and gingerly holding the back of her head. His touch and soothing words wedged open the cracks, and Super-Composed-Mabel Dam broke open, and her shoulder began wracking sobs.
He gently guided her over to a bench, where they sat and she leaned forward into the nape of his neck, still crying with her shoulders shaking as he held her close and made soothing noises.
Ugh, it’s so STUPID; Mabester, this is an awesome day, so why’re ya dorking it up with the cry-fest?
But she couldn’t help it; Weeks of apprehension were coming loose, the tension and uncertainty and fear unwinding in the certainty of his caring embrace, but they mingled with the worries and setbacks they’d already had today, along with whispered thoughts that she had stamped down and ignored earlier, but now wormed their way to the surface and took the lead, stamping down her other conflicting thoughts and repeating: It’s too good to last.
Eventually, maybe today, maybe in a week, maybe in a month or a year, but eventually he’ll realize this is bleargh to do with his twin, his sister, and then not only will you have lost this, and her mind filled with cold echoed reminders of the warm tittters she felt as he held her, of her heart racing as he gingerly kissed her in a lovey-love-you way rather than a you’re-just-my-sister way, but you’ll lose Dipper as well. He’ll probably hate you forever, and that’s assuming he doesn’t come clean to your friends, the school, or Mom and Dad.
After a few minutes, wracking sobs had gradually lessened and came out as little sad “mews” as she continued to rock back and forth, her legs tucked up to her chest. Dipper’s comforting arm was wrapped around her, his head nestled against her still-wet hair, and as he noticed her calming down, he ran a hand down the side of her face, tracing her jawbone to the edge of her beglittered lips.
“Hey there sad kitty,” he said with a sympathetic sad smile, and she managed a weak smile in return, punctuated with another sad “mew.” He leaned forward, and gave her a brief kiss on the lips, touching for just long enough that she could taste him, but pulling away right before she could do more than that.
An hour ago she would have been over the moon after him doing something like that, but that was before her dumb brain had to go and remind her of why this was a bad doomed-to-fail plan all along. She frowned, biting her lip and looking towards the tips of the distant trees beyond the park as she tried and failed to cheer herself up with thoughts of Smile Dip, puppies, glitter. Even her last resort thought, that of puppies carrying glitter-infused Smile Dip like mountain rescue dogs carried whisky flasks, failed to alleviate or even distract her from her anxiety.
She looked back to Dip, and the compassion and concern in his eyes made her heart begin to race happily and twinger the edges of her mouth upwards in a small smile, before being tamped back down as the familiar and unwanted thought of It won’t last forever echoed in her mind again. He noticed the smile fade as she broke his gaze, and held her hand as he brushed a long, damp brown curl out of her face. “Mabel, what’s wrong?”
Her shoulders shook involuntarily, betraying the false choked optimism in her stilted reply. “N-nothing, Dippingdots. Just, heh, ah, just havin’ some thoughts. Dontcha-dontcha worry about it, alright?” She gave him a forced smile that lasted for only a second as her own turmoil resurged, sparked by the look he gave her as she could see the tears shimmering at the edges of his eyes too.
He hugged her close, his grip firm, but she could hear his voice crack as he murmured to her “Mabes, I’m here. I’m here. Everything’s going to be ok, it’ll be ok. Tell me what’s wrong, and I can fix it. I love you, and you can always tell me anything.” The last sentence was slightly rushed, but she could hear the sincerity in his words.
She felt a glimmer of hope at the last bit he said, and taking a shuddering breath, said quietly “Yeah, but what about later? Dipper, this is a dream, the best dream I’ve ever had, but the sucky thing about dreams is you gotta wake up eventually.”
Looking downwards, almost too quiet for him to hear, she said “I know-I know we’ll always be twins and stuff, but I’m worried about if we’ll always be, well….this.”
She looked up to give him another forced smile, but took in a sharp breath. Dipper’s breath was ragged, and his hands around her were shaking as tears were streaming down his face. He pulled her close, and in a voice thick with tears and broken by shuddering breaths, she could hear as he struggled to speak in a relatively-steady voice.
“Mabel, ‘this’ is the best thing that I’ve ever-This is better than…Oh god, Mabel, this is better than I had imagined. You understand me in a way nobody else has, not Mom, not Dad, not Grunkle Stan, and certainly none of the girls I’ve met before or will meet in our future.” He looked up at her, his cheeks wet with tears that she knew matched her own as he continued.
“Like, you came with me for all those mysteries we investigated up at the Shack; You had my back anytime we were in danger, and we were in danger a lot,” he said, his tone becoming reminiscent as they shared a mutual giggle through the tears. “But the biggest thing is that you know me, better than anyone else, and cared about me as much as I know I care about you.”
He took her hand, looking down on it as he covered it with his other hand and looked up at her. “Lady Mabelton,” he said with a hint of a laugh at the edge, but with a sincerity that was making her mouth dry with anticipation, “You’re my twin, first and foremost, forever and for always.”
She could feel the shadows deepen, the sounds around her becoming muted. Her eyes began to shimmer with tears again, and she clenched them shut, commanding her lip not to tremble yet, not yet, despite feeling like someone took a golf club to her-
“But if you’ll have me, I’d like to be yours, forever and for always too.”
There was a tinkling noise somewhere in her head, as she cocked her head in disbelief at what Dipper said. He was giving her a look of eager anticipation, which shifted to confusion and then pain as she slapped him with enough force to sting and leave his cheek burning.
“Dipper, what the hell? Why would you say something important like that?” He gives her a nonplussed look of surprise, and then guilt as he realizes his poor choice of phrasing, but before he can say anything Mabel has dove forward into a hug, squeezing him close and murmuring into his ear.
“I love you, ya big dummy.”
He chuckles, before murmuring back “Love ya to, sis.”
They hug, letting time slip by as they occasionally kiss or nibble each other’s ear and neck, but mostly just snuggle close together in the afternoon sun, enjoying each-other’s warmth. Eventually,they lean back, smiling at each other and stepping off of the bench. A couple that was sitting and enjoying some ice cream nearby glances up at them, but then look back to their snacks wordlessly.
Mabel lets out a sigh, glad she recognized neither of them. While the biggest hurdle had just been leapt, she knew that Dipper and her couldn’t snuggle, kiss, or even hold hands once they got back closer to home. What they had now was too good to risk getting caught and losing it all.
Bedrooms, however, are free game, she thought with a pleasant warm tingle racing down her body and bringing a hint of pink to her ears.
She steered their meandering walk down a particular direction of the park they had yet to go, and the sun was starting to tickle the tops of the trees on the distant hills. She could hear Dippingsauce sigh beside her, as he saw the sun and said “Well, looks like we might not be able to hit all the rides before the park closes.”
Mabel just grins, and tugs his hand in the direction they’re already heading. “Well, while that is certainly a darn shame, could I by any chance convince you to humor me on one last ride for the afternoon?” she said, her voice slipping into a snobby aristocratic tone that was by no small coincidence reminiscent of Pacifica’s parents.
Dipper gave her a raised eyebrow, but then shrugged, going along with it for now. “Sure, why not. You’ve been itching to take me to whatever this ride is all day.”
Mabel could have sworn steam began to pour from her ears, as she let out a squeak of embarrassment and then leveled an accusing finger at Dipper. “You-You knew all along that I-Gah!” before she began pacing in a little circle, feeling her cheeks begin to blush a bright hue as she rubbed her shoulders and wished fervently for Sweatertown to hide her from her brother.
Dipper put his hands up in defense, though, saying “Hey, I figured it was a surprise, and so, I made sure not to look at the park maps or anything.”
Mabel stopped pacing, and gave him a sheepish grin. “Thanks brobro. I…um, so it was that obvious then?”
He gave her a smile and a wink, saying “Just a bit; Repeatedly avoiding probably a good quarter of the park kinda keyed me in.” Taking in her expression, she can see him grin a bit wider and he steps in front of her to block their path,. “I take it you’ve had this plan in the works for a couple days then?” he says in an inquisitive tone.
Mabel shakes her head, a little too quickly, and begins chewing on the end of a strand of hair as she looks at him. He leans backwards, a bit taken aback at her response. “Oh, wow. Weeks, then?”
Again, Mabel shakes her head, a little squeak of embarrassment coming out as she uses her hair as a curtain in lieu of Sweatertown. At this point, Mabel’s entire head and shoulders feel like they’ve been sunburned as she flushes with embarrassment.
Come to think of it, though, it might be sunburn too. We were a bit, uh, ‘preoccupied’ coming out of the house today to put on some sunscreen.
She can hear him tapping his finger against his leg, a sign of him being deep in thought, and then hears him stop. He lifts her hair and brushes it off to one side, as he says incredulously “I just remembered there was something in the paper about Watermania getting some new rides at the end of last summer. Has it been that long?”
Mabel spots an opportunity, and after a second of silence rushes out“PresidentMabelhasnocommentsbyeeeee!” as she runs past him towards the kid’s play area and water structures. Dipper laughs, and gives chase, running close behind her.
Perfect.
She abruptly stops dead in the ankle-deep water, and Dipper splashes up next to her, catching her around the waist and scooping her into the air as she laughs. He sets her down gently, but gives her a puzzled look at her mischevious grin.
“What’s with the face? I don’t trust the face,” he says, smiling but with just a tiny hint of worry. Mabel merely smiles, and glances down before looking back up to her brother. Dipper follows her gaze, and notices the enormous red ‘X’ enameled on the waterproof surface.
There is a loud CLUNK, and Dipper quickly looks up to see a giant red water pail, now filled by a slow trickle of water from an equally-giant yellow faucet, begin to ominously tilt in his direction.
Mabel grabs his shoulders, turning him so she can plant a brief kiss on his lips while standing on tiptoes, before taking an abrupt two steps directly backwards. She can see her brother’s expression, a mixture of shock, annoyance, and amusement, a split second before he is doused in a column of water. She turns and runs off giggling as the waterfall abates, and can hear her brother splutter before giving chase again.
He soon catches up to her, and after giving her a light punch in the arm, they both stop as they come into sight of the ride, and she can hear him chuckle “Ohhh.” Despite his nonchalance, she can see the excited look he gives the ride and her.
“Awesome idea, Mabes,” he says as they walk under the archway marked Tunnel of Love towards the line’s ride. “I can definitely see why you wanted to save this one for last,” he said, giving her a kiss on the cheek.
Oh, you haven’t seen anything yet.
