Hey everybody! I wrote more! Yippy! Now to bask in the glory of my adoring fans!

*Crickets*

Oh. *Awkward Coughing*. Ahem. Anyways, thanks for the review, EclipseHeart285, got me excited enough to update early! I was planning to post this on Monday, but meh. Close enough.

So, to answer your questions, EclipseHeart285 (Gosh, I hope I'm spelling it right) Bill chose Leo for one main reason: Memories. Yep. That's right. Memories. Leo has the most valuable information if you want to intentionally destroy his ship from the inside. Plus, he's the only one who could make a reasonable-ish cover story, and he doesn't have an 'annoying' girlfriend to get in the way and notice things are wrong about him. Why doesn't he just get some random Demigod and kill everybody and leave the ship alone? Gaea gave him specific instructions to destroy the ship to make sure no other Demigod uses it. I hope I answered everything alright.

Anyways, hope you like this chapter. And guess what? Leo gets to meet a special character in this chapter! Anyone knows who?

Bill led Leo (Does this made Leo Beo?) into the dining room. Before he entered, though, Beo put goggles over his eyes.

"Don't see how that would do anything. If my eyes don't give me away, your voice will." Leo thought.

"YOU UNDERESTIMATE ME, SPARKS." Bill thought back.

Beo opened up the door and strode inside, where all his friends were currently eating a meal. "HIYA EVERYBODY! HOW'S EVERYBODY DOIN'?"

Everybody looked up, Frank had his mouth open in mid-chew. Percy spoke up, "Leo, what happened to your voice?"

"WHAT? THIS? THIS IS NOTHING, FISH. SOMETHING JUST WENT WRONG WHILE I WAS WORKING ON MY ORBY-THINGY. JUST TO LET YOU KNOW, MY EYES MIGHT CHANGE COLOR, MY CHARMING PERSONALITY MIGHT SPONTANEOUSLY CHANGE, AND MY VIOCE WILL SOUND A BIT DIFFERENT. DON'T WORRY, IT SHOULD ONLY LAST A FEW DAYS!" Leo, with some shock, felt his memories being searched. Bill was trying to figure out what Leo would say in this type of situation using past memories. Leo couldn't help but be impressed.

"Don't call me fish. What were you working on?"

"I WAS TRYING TO FIGURE OUT HOW TO CHANGE MONSTERS' PERSONALITIES TO MAKE THEM NOT WANT TO KILL US. BUT IT KIND OF BLEW UP IN MY FACE, SO SOME OF THE EFFECTS RUBBED ON ME. IT SHOULD GO AWAY IN A FEW DAYS. HEY! IS THAT HUMAN FOOD?" he pointed at Frank's cereal.

"Umm, yeah?" Frank said nervously.

"GREAT!" Beo ran over and grabbed Frank's cereal. He picked it up and dumped it all over Leo's face, "HAHA! THIS TASTES DELUX!"

Frank backed up nervously, "Heh, heh. Yeah." Leo felt bad for him. And himself. Bill was making Leo look weirder than normal.

"Leo, are you sure you're okay?" Piper asked. "No! I am not!" Leo screamed in his head.

"OF COURSE I AM PIPES! PERSONALITY FLAWS, REMEMBER?" he felt Bill looking in his memories again, "DON'T WORRY! I'LL BE BACK TO MY CHARMING SELF IN NO TIME! NOW I NEED TO GO WORK ON MY LITTLE TOY THAT WE CALL A WAR SHIP."

Beo walked out of the room and shut the doors, leaving his concerned friends behind.

"They'll figure out something's wrong, Bill," Leo thought triumphantly.

"HAHA! OF COURSE THEY WILL! BUT BY THAT TIME, IT WOULD ALREADY BE TOO LATE!" Bill thought back.

"What do you mean by that?"

"OLD EARTHY SAID TO DESTROY THIS SHIP AND KILL YOU'RE FRIENDS. BUT I CAN DO THAT THE FUN WAY, OR THE EASY WAY."

"What's the fun way?" Leo thought nervously.

"THE FUN WAY IS MAKING THEM TRUST YOU, THEN KILL THEM ONE BY ONE IN PERSON WHILE THE SHIP IS FALLING OUT OF THE SKY. THAT WAY I CAN EXPIERIENCE THEIR FULL SHOCK. HAHA! I HAVEN'T HAD THIS MUCH FUN IN AGES!"

"You don't know how to destroy the ship. I made it so no one can deliberately destroy it. I made backup systems. You would need to sleep and rest."

"SEE SPARKS, THAT'S WHERE YOU COME IN."

"Me?"

"WHERE I WENT WRONG LAST TIME WITH PINE TREE IS THAT I GAVE NO CONSIDERATION TOWARD HUMAN NEEDS. BUT WITH YOU, I CAN KEEP MYSELF FROM FEELING TIRED WHILE YOU'RE THE ONE WHO SLOWLY RUNS OUT OF ENERGY. OF COURSE YOU WOULD EVENTUALLY BURN OUT FROM EXISTANCE, BUT MEH. I'LL FIGURE THAT OUT LATER." Beo walked toward the wall and punched as hard as he could, "HAHA! I LOVE THIS SACK OF FLESH!"

Leo groaned in pain but was confused when he saw the wound slowly fade from his hand. "What the-" there was another jab of Leo mentally grabbed his hand again. He looked down at his ghost hand and saw the wound appear there. "What is this?" Leo asked fearfully, clutching his broken ghost hand.

"I LIKE TO FEEL PAIN, SPARKS, BUT I NEED THIS BODY IN TIP-TOP CONDITION. AS A GHOST, YOU CANNOT HEAL YOURSELF. YOU'RE STUCK WITH THAT HAND UNTIL YOU REGAIN CONTROL. WHICH WILL BE NEVER!"

Mental Leo cradled his hand, while a few tears slipped out of physical Leo's eye. Then he had an idea. He could warn his friends using his eye! It seemed like that was the only part Bill had no control over. Maybe he could cry, or blink Morse code, or-

"NICE PLAN SPARKS!" mental Leo jumped, "BUT YOU'RE FORGETTING WE'RE SHARING THIS MIND! I CAN SEE YOUR THOUGHTS! BESIDES, I HAVE THESE GOGGLES ON."

Leo growled, "I'll find a way, Bill! You can't keep me in here forever!" then he realized that he spoke from his own mouth. Mental Leo gasped and tried again, but was unable.

"WOAH! SOMEBODY'S FEISTY! LOOKS LIKE YOU HAVE SOME FIRE IN YOU, SPARKS. BUT I'LL TAKE CARE OF THAT!" Beo punched the wall again with the same broken hand, and Mental Leo screamed. "HAHA! I CAN SEE WHY OLD EARTHY THOUGHT YOU WERE IMPORTANT. WITHOUT YOU, THIS QUEST WOULD BE A MESS. LIKE SHOOTING STAR AND PINE TREE. PINE TREE IS THE ONE WHO IS DUMB ENOUGH TO GET HIMSELF IN AND OUT OF TROUBLE, BUT WITHOUT SHOOTING STAR, HE WOULD BE CRAZY (OR DEAD) BY NOW!"

"Who is this Pine Tree you keep talking about? Is it another screaming head?"

"HAHA! YOU'RE FUNNY, SPARKS! NAW, HE'S JUST THIS ANOYING KID THAT KEEPS MESSING UP MY PLANS. HE, SHOOTING STAR, SIXER, AND FEZ. GLASSES USED TO BE A PROBLEM, BUT HE'S LONG GONE BY NOW."

"What happened to Glasses? Is he dead?" If Bill killed 'Glasses', he would probably kill Leo too.

"GLASSES ISN'T DEAD. BUT HE MIGHT AS WELL BE. HE'S INSANE AND LIVES IN THE DUMP. HAHA! THE LOOK ON HIS FACE WAS PRICELESS WHEN HE CAME THROUGH THAT PORTAL!"

Something in Leo's mind clicked. These were all nicknames. Sixer, Shooting Star, Fez, Pine Tree, Glasses, were all just nicknames. He was Sparks, Piper was Pipes, and Percy was Fish, and Gaea was 'Old Earthy'. "Do you have nicknames for all people?"

"ONLY THE IMPORTANT ONES. YOU KNOW WHAT I WANT TO DO RIGHT NOW? GO TICK OFF TIME BABY. BUT I CAN'T DO THAT RIGHT NOW IN THIS SACK OF FLESH! OH WELL, I GUESS I NEED TO DO SOMETHING EQUALY ENTERTAINING. HOW 'BOUT SCARING PINE TREE?"

Beo reached into the tool belt and brought out a wrench. He held it out and hit himself over the head. They blacked out.

Leo rubbed his mental head, "What the Hades was that for?"

"WE NEEDED TO ENTER THE DREAMSCAPE. CAN'T DO THAT WHILE YOU'RE CONSCIOUS!"

Leo looked around the grey landscape, "You could have just fallen asleep, you know."

Bill ignored him, "I KNEW SHARING A BODY WITH YOU WOULD BE HELPFUL! I CAN ENTER THE DREAMSCAPE IN HUMAN FORM AND USE MY POWERS! THIS IS DELUX!" Beo floated up and shot things randomly. A bed lamp turned into a flamingo, and a rug turned into a two horses fused together at the heads. "NOW LET'S GO FIND PINE TREE'S DREAMS! HE IS SO FUN TO TALK TO!"

Beo floated pass what seemed like portals. He stopped at a particular one that showed two siblings (they looked like twins) running from what looked like a giant gnome. "HMM. LOOKS LIKE PINE TREE IS HAVING A NIGHTMARE. LET'S GO HELP HIM!"

They floated through the portal and the dream instantly turned black and white. Everything vanished leaving the boy alone. He looked around confused, "Mabel?" he called.

Beo took off his goggles and put it back into the tool belt. "WELL, WELL, WELL. LOOKS WHO WE HAVE HERE!"

Startled, the boy looked back. He looked at Leo up and down, then he saw the eyes. "Bill!" he gasped.

"THE ONE AND ONLY!"

"What do you want?"

"WHAT? CAN'T A DREAM DEMON VISIT AN OLD BUDDY?"

"We are not buddies. Whose body is that?"

"THIS IS SPARK'S BODY. HIS BODY IS DELUX! WANNA SEE WHAT HE CAN DO?" Beo shot a flame at the boy, and the 'Pine Tree' dodged.

"AHH!" he screamed as he covered his head, "What the heck was that?"

"YOU SEE, PINE TREE, SPARKS HERE IS A VERY SPECIAL KID. HE CAN-"

"What's wrong with your eyes?" 'Pine Tree' interrupted.

"THAT'S VERY RUDE, PINE TREE. FYI, I CAN'T TAKE FULL POSSESION OF THIS KID'S BODY."

"Why not?"

"BOY, ISN'T SOMEBODY NOSEY TODAY?" Beo snapped his fingers and a giant nose appeared out of nowhere and dove toward Pine Tree. He yelped and ducked, and just before it hit him it exploded into confetti.

Pine Tree scowled and brushed himself off. "What are you planning, Bill?"

"ME? I'M NOT PLANNING ANYTHING! I'M JUST FINISHING MY END OF THE DEAL."

"What deal?"

"LOOK KID. EVEN FOR ME, I NEEED TO RESPECT THE PECKING ORDER. FOR NOW, AT LEAST. WHEN OLD EARTHY COMES TO MAKE A DEAL WITH YOU, YOU LISTEN UP."

"Who's Earthy?"

"NOBODY YOU NEED TO WORRY ABOUT. HEY! NEED ANY TIME SLIME?" a bucket appeared above Pine Tree's head and spilled out.

"Ahhh!" Pine Tree screamed. He ran out of the way and the ground where the slime landed caught on fire and disintegrated.

"You're crazy!" Leo thought, "He's just a kid!"

"NO ONE ASKED YOUR OPINION, SPARKS."

"Who are you talking too?" Pine Tree asked.

Bill realized he talked out loud, "JUST MY NEW FRIEND UPSTAIRS. WANNA SEE MY NEW PET UNIGERBIL?" a gerbil appeared in a puff of smoke, only this gerbil was the size of an elephant. And it also had a unicorn horn. "Go figure," Leo thought. It squealed and charged at Pine Tree.

"Ahhh!" Pine Tree covered his face and stumbled backwards. The gerbil raised his claw to smash the boy but Bill snapped his fingers and it curled into a ball and sunk into the ground.

Leo thought of something. "You can't hurt him here, can you?"

"HAHA! DON'T I WISH! I JUST LIKE PINE TREE TO REMEMBER WHO'S ON TOP OF THE TRIANGLE." Bill thought back.

"Why are you here, Bill?" yelled Pine Tree. Leo was impressed by this kid's bravery. He was just chased by a giant unigerbil and was already back to negotiating.

"LOOK, PINE TREE. I HAVE BIG PLANS COMING, AND I'M GIVING YOU ONE LAST CHANCE TO BACK OUT OF IT. I'LL KEEP YOU AND YOUR FAMILY SAFE. WHEN MY PLANS ARE PUT TO ACTION, I'LL PUT YOU AND THE REST IN A SAFE TIME BUBBLE, WHERE YOU CAN BE WHOEVER YOU WANT TO BE AND SUMMER LASTS FOREVER. YOU, SIXER, FEZ, ICE BAG, GLASSES, LLAMA, SHOOTING STAR, AND ALL THE REST! IT WILL EVEN KEEP YOU SAFE FROM OLD EARTHY. ALL YOU NEED TO DO IS STAY OUT OF MY BUSINESS AND SHAKE MY HAND." Bill stuck out a hand.

Pine Tree hesitated, "You'll protect everyone? Mabel? Wendy? Soos? Grunkles Stan and Ford?"

"YEP! EVERYONE ON THE WHEEL!"

"Don't do it!" Leo thought desperately.

Dipper thought for a moment. He hesitantly stuck out a hand, and it caught on fire.

"No!" Leo thought.

"YES!" Bill thought.

They were about to shake, and Leo moved his eye around wildly, trying to signal to the kid. But he didn't see. The hands were only a few millimeters away from contact when Pine Tree pulled back. "You're lying," he whispered.

Leo felt Bill's rage course through him. Bill shook with fury, then he calmed down, "WHATEVER YOU SAY KID. YOU'RE LOSS." Bill punched a wall with the wounded hand. Mental Leo grasped his hand and screamed in pain, tears dripping out of his one eye. Since the hand couldn't heal, the pain never ceased. He was literally punching a wall with fresh broken bones. It didn't swell, go numb, slowly scab. It stayed fresh. And it hurt like Hades.

Pine Tree saw the tears and the healing wound, "What did you do to him?" he asked with concern.

"SOMEBODY NEEDED TO PAY, AND YOU BETTER THANK THE UNIVERSE IT WASN'T YOU. AND REMEMBER: REALITY IS AN ILLUSION THE UNIVERSE IS A HOLOGRAM BUY GOLD KIDS BYE!"

They disappeared with a zap, and Leo grit his teeth, "It's bad to punish others for your problems, you know."

"I KNOW, BUT IT'S SO MUCH FUN!" Bill thought gleefully, "PREPARE YOURSELF KID. WE HAVE COMPANY WHEN WE WAKE UP."

Hoped you liked this okay! If you think any of the characters are to OC, please give me constructive tips on how to make them less so. It's surprisingly hard to write for funny characters while they're being possessed by evil demons. Speaking of which, did I do Bill's character okay? Hope I did! I tried to make him as random and weird as possible. Am I making the difference between, thinking, talking, and possessing to confusing? Because if I did, I can give you a graph thing in my next chapter. And guess what? I forgot to put a disclaimer in the last chapter! So sorry big time companies who can sue the shiz out of me! I do not own Gravity Falls or Percy Jackson! They belong to Disney and Rick Riordan. Please forgive me! I put a disclaimer in the description box! That must count for something! Right? RIGHT? Anyways, finished my freaked out rant there. So, followers and favs are great, but my favorites are reviewers! Review!(And, I'm just taking a shot in the dark by saying McGuckit is Glasses. Don't start flaming me if I'm wrong. I obviously wrote this before whatever episode reveals Glasses identity. And this story takes place in no particular book. You can imagine it to be in whatever book you want [besides The House of Hades XD])
