Let's all give a shout out to "A very angry ravage", who's comment about his life not being complete without an ending to this story drove me to write this next chapter the same night I read his comment.

Chapter... Er... I forget, what chapter is this again...?

Wham.

What a beautiful day. Sunshine, birds singing, flowers blooming, everything really you could hope for during your summer holiday. On days like these, it was good to be on summer vacation.

Wham.

What was that noise…? Thought a part of Mabel's glittery brain. The young girl slowly awaked from slumber after a well-deserved night of sleep. Her hair, of course, was a mess, and her pajamas still barred scares from previous sleep-overs. But she liked it that way, you know. It gave her wearing a pleasant smell.

Wham.

Ah, but she were eventually fated to wake up, wasn't she? And the yawn she had just manifested was merely further proof of that fact. Shamefully giving up on sleeping for an eternal period of time, she rose from her sheets and directed herself towards the door of her shared room.

Wham.

Oh, but wait! A shiny object on the edge of her wardrobe caught her not fully-awakened attention. Her camera. Ah, yes. Her camera. She hadn't used that in a while, had she? Her parents would surely scowl her for that. It was important, they said, to keep track of your exciding life every step of the way. Needless to say, she'd obediently put together a scrap-book in honor of her servility. It was agreed, then. She would take her faithful camera with her that very day.

Wham.

She asked herself though, as she twisted the door knob and wondered down the stairs, what sort of fun activity she would come across on this glorious day. She hadn't seen a snake in while. Snakes were fun. She wished for a snake, then. Or a snack, depending on the circumstances. It was funny that those two words resembled each other in such a way. She wondered if she'd ever have the occasion to make a pun on the matter one day.
When she reached the end of the hallway however, something caught her attention. Remember that strange banging you heard earlier? Yes, that one. Don't even pretend you don't know what I'm talking about. I wrote it about five times in the last paragraphs. Well now Mabel knew where it originated from, for her beloved brother was busy.

"Haha!" the eager boy yelled as he happily threw himeself once again against the entrance wall. "Haha!" he continued, repeating the same dance a few times in a row like it were the best thing he'd ever occupied himeself with. Flies were really onto something, he seemed to aknowledge.

"Mabel!" Wendy called upon noticing her, "I think Dipper is broken…
- Yea!" Added Sooth. "It's usually funny, but I'm starting to feel bad for him... The little dude's been doing that for a while now; I think he's trying to walk out the door..."
As if to add to the handyman's last declaration, Dipper suddenly seems to find the floor very attractive, both in the scientific and non-scientific definition of the term. But of course, as of any decent broken toy worthy of the name, he kept rather joyously walking towards the imaginary door he strived for, which was obviously in front of him, only this time sideways.
"Hehe..." giggled Sooth, forgetting about human empathy for a minute there to the profit of sheer amusement. "On second thought, now he's sideways, this gives a whole new perspective on how entertaining this is. Like playing the same videogame all over, just with a different skin.
- Guys, this is serious!" Intervened Wendy, upset about the population's lack of reaction and ESPECIALLY at a certain little girl that had apparently found in her twin brother's behavior a decent reason to practice her filmmaking skills. Dipper was her friend after all, and she was worried. "Something's wrong with Dipper! Shouldn't we call a doctor?"
Incedentally - and, also, rather ironically - a wild Stan appeared at the corner of the hallway, possibly on his way to the bathroom and visibly very non-preoccupied with the commotion.
"Grunkle Staaaan!" Shout out Mabel a her great-uncle, praising his good timing. In fact, to be honest, Wendy's argument made sens, and her filmmaker's instincs were starting to wither away as she slowly starting to ponder the question of Dipper's health. But admitting she couldn't differenciate her brother's behavior when he was just happy-go-lucky and when he was mentally ill was slightly embarrassing. Therefore, seeking advice from an old man with trust issues and a slightly sadistic side to him soudned like the best course of action.
"Grunkle Stan, in you WISE opinion, has my bro-bro been acting weird lately?"
And Stan, who had obviously been bored long before anyone had ever had the idea to adress him, turned an oh-so-obviously-bored look towards his step niece, then, since she happened to mention it, to whatever you'd call that child bouncing of the floor like a fish in desperate need of oxygen who'd never been happier in his life. Stan stared at the young pre-adolescent as the boy didn't react to the bug he'd accidentaly swallowed because of his wide open mouth. Then, in some very distant memory of his non-interested mind, he seemed to vaguely recall something involving a prank, concluding that no matter what… This… Was, it wasn't any of his business. He'd just coincidentally stumbled upon this sequence of events because of his quota in needs concerning the bathroom due to his obviously young age. So in all reasonable logic, the same sequence of events could very well panel out without his participation. Besides, the kid looked healthy.
"Nope," he answered in short, "Nothin' wrong with him at all."

And then proceeded to the bathroom.

Mabel being satisfied with that answer, now that her ethical judgement of the situation was out of the way, she resumed her filming activity. She would call the following footage "My brother has a brain tumor - the sequel".
And just in time, to, for the constant mumbling the damaged boy was uttering were now turning into words as his specie had just figured out how hands can be used as tools to assist you in standing back up again.
"But… She's amazing!" resumed Dipper, as, apparently, this was following a rather complex reasoning. In the next phase of his developpment, he was seemingly walking around in circles like he had just done a scientific discovery. "How can I have been so blind? She's fantastic!"
In a surprising turn of events, he suddenly turned towards his sister's filming camera with intensity, and addressed her with a: "Mabel, do… Do you think she's go out with me?"
He bursted out in laughter like he'd just said the best joke in the multiverse.
"Nah, you know what? I'll just ask her directly."
And before Sooth, Mable, or even Wendy could ever try to stop him, he turned around to face to wall and whammed once again with full force against it, truly believing that's where the door stood. "Haha! Oh man, this never gets old!" he yelled. "I'm okay – no, I'm BETTER than okay!" And somehow, following that last declaration, Dipper did, in fact, manage to walk out the famous door he'd been desperatly looking for. And all his friends and family stoikly starred on his way out, perhaps doubting there choice of not going after him upon hearing a care tire almost run over the happy child.
"I'M OKAAAAAY!" they nevertheless heard.
"Is... Dipper going to be okay...?" said Wendy, worried about the danger they'd just set off into the wild to run free.
"I sure hope so!" Answered Mabel with a professional tone, "I can't wait to show him this video once he's back to normal. I can make a fortune through blackmail!"
"OH MY GOOOOOOD!" resonnated the fan-girl's flavor of Dipper's screaming, "PACIFICA! THERE YOU ARE!"
