Hi! I'm glad to be back! Get ready for a great new challenge for Dipper and Mabel! Today we are focusing on the third and final task: 3 tablespoons of magic water! Will they succeed? Read to find out! Reviews:

Aliqueen: Hahaha yeah, no kidding! I scared myself a little when I wrote that!

ImpossibleJedi4: Aw, thanks! I'm glad you liked that, Mabel just seems like that person who would take charge and be serious (but only if absolutely necessary!) in a situation like this.

Dipper's P.O.V.

I'm glad that's over with. Those pills actually helped us for once. For the first time on this life-or-death mission, I actually have a spark of hope. Out of the 21 days I was given to live, 14 still remain. That gives us 2 whole weeks to complete the final task and get back to the hospital. We can do this!

Mabel's P.O.V.

Dipper is a lot happier than usual. Maybe the whole 'almost dying' thing really gave him a new perspective on life. Or maybe the pills gave him the case of the grumpy grumps. Either way, with a cheery partner, this was going to be a whole lot easier.

"Hey, isn't the water in a forest?" I ask.

"I think so. Why?" Dipper wondered.

"Because we're in one!" I say.

"Ohhh. I don't know why I didn't notice-"

*Thump*

"DIPPER!" I scream.

My brother lay face down in the long grass, twitching uncontrollably. His pills! Dipper needs them to help stabilize him. But they're gone... uh oh. We might not have as much time as I thought. But as quickly as it started, it was over.

"Uhhhh... what just happened?" Dipper questioned, sitting up. "Where am I?"

"Dipper!" I rush toward him and give him a bear hug. "Don't scare me like that!" I scold.

"But what? How-"

"Doesn't matter. We just need to find a well and get outa here!" I smile.

"Agreed. But where exactly is here?" He asked.

"I said it before. Doesn't matter." I sigh. "Lets just get movin'."

He nods, and I start off, Dipper close behind. We keep a quick pace, but unfortunately it gets dark and we have to set up camp for the night.

"I'll take first watch." I frown. "Stay close to me."

He falls asleep, and I sit up, awake. Thinking. Where could it be? The well couldn't be far, could it? Maybe we passed it. It's a pretty big forest after all. I glance at Dipper, wondering how much time he actually has left. Clearly he won't last 2 more weeks, not in this state. Maybe 1 week? Maybe less? I sit, lost in my thoughts, until Dipper taps my shoulder, signifying that my shift is over. I immediately tip over, and fall asleep.

I am awoken by a frantic Dipper shaking me violently, the fear clearly shining in his eyes. I yawn and squint at him, wondering what was wrong. Then I saw it. Or should I say him. There he was, the 'unspeakable horror' the nurse warned us about. An old enemy. Bill Cipher himself.

"Bill?! Are you our final challenge?!" Dipper shouted, trying to get the evil triangle's attention.

"Pine Tree! It's about time, I've been waiting for you. I see you dragged Shooting Star into it too?" He drones.

"What do you want, Bill?!" Dipper yelled angrily.

"Oh, nothing much... I just came to watch you suffer." He smirks.

"What? But aren't you supposed to be protecting the well? Our quest?"

"Oh I know all about your little 'quest'. I was the one that sent that butterfly to poision you, to get rid of you once and for all. I knew that if you were gone, it would destroy everyone around you. You are a ticking time bomb... but you will kill anyone within 100 feet of you if you fail. So many will die." He explained. "But about your quest, I'm not the horror. You haven't gone far enough yet."

"So you just came to watch?" I ask.

"Yeah Shooting Star. That's why I'm here. To watch the flesh bomb blow."

I glance at Dipper, who looks a little uneasy. I don't blame him, though. To hear news like that... I'm surprised he didn't have a bigger reaction. I grab his arm and start walking.

"Alright, Bill. You listen to me, you are going to tell me where to go to find the well, and then you are going to LEAVE US ALONE. Is this clear?" I demand.

"Hahaha, you think you have a chance! How cute. I'll tell you what, I'll help you. It'll still be fun to watch you die in the hands of Shadow." He chuckles. "Go straight ahead for a few minutes, turn left, then left again, until you find the well. It'll be near a big tree, the biggest in the whole forest."

I turn on my heel and Dipper follows. We follow the directions Bill gave us, until we reach the big tree. The well is exactly where Bill said it would be, and nothing is there to stop us. We carefully measure out the 3 tablespoons and pour it into a small Tupperware dish, and cover the top. We start walking home when an icy feeling overcomes the air. The sky goes dark and the clouds turn black. A dark figure appears out of nowhere, then disappears completely. I turn to look at Dipper, but he's not there!

"Mabel! Help!" A strangled voice cries for help. I'd know that voice anywhere. It's Dipper!

"Dipper?" I call. I can't see him.

"Over here!" He calls back. His voice is coming from the tree. But I still don't see him.

I dash to the tree, and look all around it.

"I'm in the tree!" His muffled voice shouts.

"How'd you get in there?" I ask.

"I don't know. One minute, I was standing behind you. The next, I was in a tree!"

"Ok, relax, I'm going to get you out of there. Just stay put." I try to calm him down.

"Where can I go?" He asks sarcastically.

"Just shut up." I growl.

I pry open the tree, which turns out not to be a tree at all, but a containment center. Almost like a storage box.

"Thanks." He whispers.

"Thank me later. We've got to get outta here before that 'thing' comes back!"

"Shadow." Dipper murmurs.

"What?"

"Shadow. That's what Bill said it was called." He says. "Whatever it is, it's powerful. But I couldn't feel it's touch when it put me in the tree jail. Maybe it's a spirit?"

Just as Dipper finishes his sentence, 'Shadow' peeks out of the bushes and flies toward us, and he's fast. It swirls around us like a tornado, and everything goes black. It's pitch black for miles, and nothing can be seen. So we both pull out our flashlights, and turn them on. There's a loud hissing noise, and where the light is shining turns to light. Pure, white light, and it dissolves the 'Shadow' until just it's original form is left. Then, even that disappears. Leaving the two of us standing in a circle of brightness. Eventually, the light fades away, but we are taken with it!

We struggle to escape, but the light is strong. We are stuck in the light for a few minutes, and Dipper slowly starts to fade away. I grab onto him and hold tight, and the light fizzles out in a shower of sparks. And where are we standing? The hospital room, with all the ingredients and Dipper. He collapses into my arms, a dark purple color rapidly climbing up his body, until his skin is completely purple.

I scream, and a passing nurse gasps. She was the nurse from before, and gives me a frantic look. I hand her the ingredients, and she mixes them together, and injects it into Dipper. His body shudders, then he gasps for breath and his eyes open wide. I pick him up and lay him on the hospital bed, and he slowly regains his strength, until he is strong enough to sit up. By this time, Grunkle Stan is here, along with Ford and Soos. Apparently the time we were stuck in the light was more than I had originally thought. We were in there for a couple of days.

All of us look at Dipper worriedly. None of us knew for sure if the formula worked, so we were tense. Then, suddenly, he jerks up into a sitting position, and coughs. He glances at Ford, Soos, and Stan, but when he saw me, Dipper sighed contentedly. All was good, at least for now, and that was ok by me.

Why did I end it like that? Because I might make a sequel! If you think that's a good idea, then comment below. Plz R&R, have a great day, and vote on my poll if you have time. Thanks!
