Beware Of Brother...

Those words repeated themselves in Bill's head over and over, as he laid on his bed and stared up at the ceiling. He had hid the mysterious paper underneath his mattress, and was pondering whether to let Will know of it's existence. He supposed he had to tell Will soon enough, he just needed time to process it first.

Beware Of Brother...

Those words made no sense. Which brother?

Could it be Kill? Bill already knew to be weary of him, this warning would only state the obvious. Perhaps, it was addressing his eldest brother? What was his name? Tim?...Ted?...Tad!

Bill's brow furrowed. He recalled that Dipper mentioned Tad was a force to be reckon with, the blond hated to have another powerful enemy. Also, why would this Tad person appear after what Bill assumed to be centuries of him missing in action?

For now, Tad was the only logical option. If not, that only left Will...

That can't be right, Bill thought.

Will was the pinnacle of innocence. Even if (a very big if) the younger twin intended to hurt Bill, it would be impossible, since Will would be easy to stop.

Though, Bill began to notice that his brother was growing stronger as this summer went on. Will managed to survive many obstacles, and he was almost unrecognizable to Bill when it came to facing danger. Bill supposed, that if Will was planning to hurt him, maybe stopping him wouldn't be as easy as he thought--

What was he thinking!?

Will was his brother. The two were glued to the hip since their birth. The blue haired boy would never hurt him!

Bill heaved a sigh, growing a headache. This also left the mystery of who wrote this message, as while drawing the detailed blueprint. Could it be the Pine twins? Or maybe Stan? Did either of them wanted Bill to follow these blueprints? If so, why would they do it anonymously? And what was this contraption they wanted him to build?

Seriously, do I look like an engineer?, Bill thought, bitterly.

"Hey, Bill?"

His mangled thoughts were put to a halt, and he turned towards Will, who had just finished getting dressed, along with a name tag pinned on his sweater.

"Stan might dock your pay, if you're late for work again," Will pointed out.

Bill rolled his eyes. "You say that, like he pays us."

Will chuckled in return. "Yeah, I suppose so," He admitted. Slowly, his face morphed into worry. "You've been looking at the ceiling for a while now...is something on your mind?"

Should he tell him now?

Bill decided not to. Mostly, because he didn't have the sanity or the nerve to show Will the paper. He'll make sure to do it later, though.

"Nothing in particular," Bill answered, trying to sound casual.

Will smiled, but his eyes were still clogged with worry. "Remember, if there's something on your mind, you can always tell me."

The way his face held genuine concern and care, convinced Bill that Will was definitely not the brother the paper was referring to. So, like before, Tad was the only one to fit the role...wherever the hell he was.

"You should get dressed," Will suggested, heading for the exit. "I'll see you downstairs."

Bill only nodded, not even looking his brother's way, as he heard Will climb downstairs. The blond reached down, grabbing the corner of paper that stuck out from under his mattress, and pulled the whole thing out. He lifted it to his face, and stared at the complicated blueprint once more.

He clutched the corners of the paper, causing it to crinkle under his grip.

Whoever wrote this, I don't like you.

❇❇❇

A while later, the Mystery Shack was open, and the twins took their places. Will was counting money behind the counter, while Bill was helping a customer, who happened to be Tyler.

"Which one do you think will suit me better?" Tyler asked, holding up two similar looking shirts with wild cats on them. "Panther shirt? Or puma shirt?"

Bill looked between the two thoughtfully. "I dunno, they both look so good. How about you purchase them both?"

"And then I can stitch them together. Great idea!" Tyler beamed.

"Uh, sure. And while you're at it, you can buy some of these rare crystals," Bill said, pointing to a bowl displayed on a table nearby.

Tyler peered at the contents. "That looks a lot like broken glass."

"Well, that might seem like it, but that's because they're really fragile crystals," The blond said, coolly. "If you break some against your floor, that's good luck. More so, if you step on them barefoot."

"Ooh! How much?"

"50 dollars," Bill replied, with a smirk.

Tyler dug in his wallet, and pulled out a wad of cash. "All I got is 60 dollars at the moment, you can give me change in return--"

"60 dollars works," Bill said, swiping the money from him. "Thank you for shopping at the Mystery Shack."

After that, Tyler cheerfully took his products and exited the store. Bill leaned against the counter, handing the money to Will.

"Make sure to give half of it to us," The blond said. "Don't want Fez to hog it all."

"It's kinda weird that an intergalactic deity would need money," Will pointed out, while sorting the cash.

"The guy has committed tax fraud in several dimensions, he's a little screwed up in the head," Bill remarked.

So far, it seemed like it would be another normal day of work. Until, the front door swung open, and caught the attention of the twins. Grenda and Candy stepped in, and they were carrying Mabel, who was staring blankly.

"Oh my gosh, what's happening here?" Will gasped.

"Quickly!" Grenda shouted, urgently. "We have a code Upsidedown Smile! Code Upsidedown Smile! This is not a drill!"

"There are over a million words in the dictionary, and none of them can describe my confusion right now," Bill said.

Will quickly went up to Mabel, who looked very depressed at the moment. "Mabel, what's wrong?"

"It's Mermando..." She whimpered. "He's getting married!"

Mabel suddenly handed him a piece of paper, and Will looked down at in puzzlement. "Is that a manatee?"

"I know! And she's beautiful!" Mabel cried. "Just when I thought I had a chance with him, my dreams of romance are crushed once again!"

"She needs to hug something cute, stat!" Candy declared. "Will, find Gompers! If not, then come closer so Mabel can crush you in her embrace."

Will immediately backed away. "I have a better idea," He said, quickly. "I was meaning to tell you earlier, but I found this concert that you guys might like."

"Concert?" Mabel questioned, standing up on her two feet. "Who's playing?"

"Hold on," He said, reaching into his pocket. Will pulled out his phone, and after tapping on the screen, showed them a picture of a group of identical blond young men. "They're called Sev'ral Timez. They're supposed to be performing at the town's Civic Center and Buffet. Plus, they're selling tickets upfront."

Mabel's face morphed into an awestruck expression. "Sev'ral Timez is playing here?" She breathed, then squealed loudly. "They're only my favorite band in the mortal realm!"

"I know right?" Grenda agreed, excitingly. "My favorite is Deep Chris!"

"He's the phat one," Candy giggled.

"You know those kinds of boy bands are fake, right?" Bill remarked. "They were probably cooked up in a laboratory or something."

"Make fun all you want, but nothing is going to ruin this," Mabel smiled.

"So, does this make you forget about the situation with Mermando?" Will asked, hopefully.

"More than ever! Thank you," She told him, gratefully. "Are you coming with us?"

Will shook his head. "I don't really like big crowds, you guys can have fun without me."

"Well, you can at least help us get ready," Mabel grinned.

Then, she grabbed his arm and dragged him away, followed by Candy and Grenda. Bill watched them leave, with a furrowed brow.

"Sure, just leave me to work by myself," Bill grumbled, to himself.

Maybe, I can close early, He thought. Stan isn't here to supervise, anyway.

The blond was about to move towards the door, when it swung open again. This time, Dipper and Wendy walked in. The redhead wore a sour expression, while the brunette regarded her worryingly.

"What's with the face, Red?" Bill asked her.

"Robbie," She groaned, leaning against the counter.

Bill tilted his head. "Uh oh, trouble in paradise?"

"The problem is, is that he's been really distant with me," Wendy complained. "He keeps sneaking off to do Axolotl knows what, and doesn't even bother to hang out with me. I know he's a busy guy, but shouldn't we at least have a moment alone together, since we're dating?"

"I keep telling you, he's a trash person," Bill insisted. "If he doesn't treat you right, you should break it off with him."

"I have to agree with Bill," Dipper said, gingerly.

Wendy frowned. "I know Robbie isn't the friendly type, but you guys don't know him like I do," She said. "But...I suppose--"

"Hey, Wendy!"

Bill rolled his eyes. "Speak of Mr Fingerless Gloves."

The three turned, and saw the Cupid standing before them. As though Dipper and Bill were invisible to the eye, Robbie pushed past them, and gazed adoringly at Wendy.

"Wendy, I was thinking the two of us could go to Lookout Point tonight," Robbie suggested.

Wendy narrowed her eyes at him. "Are you kidding me?"

"Huh?"

"It's been weeks, since we actually went on a proper date, and every time I asked you for some quality time, you blew me off! Now, you suddenly noticed that I existed. Seriously, what's up with you, lately?"

"Bill, maybe we should leave," Dipper said.

"Why, this is the most entertained I've ever been," Bill countered.

Though, it seemed that Dipper wasn't giving him a choice, as he dragged the blond towards the storage closet. He tossed Bill inside, before stepping in himself. Bill was about to scold the brunette, when he realized Dipper was still eavesdropping on the conversation. Bill joined him, trying to ignore the Guardian's body heat, while resisting the urge to get closer.

Robbie stuttered when he talked. "I didn't mean to ignore you, I swear," He insisted. "I've been...dealing with a lot, lately. But, I'm here now!"

Wendy heaved a deep sigh. "Robbie, this isn't the first time you made empty promises. I think...I think we should break up."

Bill looked over Dipper, and the brunette looked ecstatic. An ache made it's way into the blond's chest, and he forced himself to listen more to the two outside.

"OK, listen before you do anything crazy," Robbie said, then dug in his pocket. "I have something for you."

Bill and Dipper peered out of the room a little, and saw the Cupid pulling out a CD with a creepy looking case. Robbie also took out a player, and puts said CD inside it.

"I wrote a song for you," Robbie told Wendy, innocently.

Wendy still looked upset, but her expression slowly turned into curiosity. Robbie cleared his throat, then began to sing when the music emitted from the player.

"When I think about you, I feel feelings so deep. I'm tossing and turning, and you know I'm losing sleep."

"Oh, barf," Bill gagged, and Dipper hushed him.

Robbie didn't seemed to hear them, and continued singing the last verse. "And you know I'm going crazy, when I look into your eyes. Just listen to this song, and you'll be hypnotai-ai-ai-zed!"

As the song finished, Wendy's eyes grew wide, like she was in a trance. Right after, the redhead rubbed her eyes, and her face held a kind smile.

"Maybe, I was being to hasty," She said. "I'll give you another chance."

"That's good to hear, babe," Robbie said, leaning and hugging her around the shoulders. "How about we go sightseeing around your favorite part of the forest?"

"Sounds good," Wendy agreed.

Then, the two left the shack, while affectionately glancing at one another. Meanwhile, Dipper and Bill came out of the closet, dumbstruck.

"What just happened?" Bill questioned. "That song was terrible, and suddenly Wendy is all lovey dovey with him because of it? I knew her standards are low when she dated Robbie in the first place, but come on!"

Dipper nodded in agreement, then turned to the counter. Robbie had seemed to left his player and CD behind by mistake. Dipper walked forward, and picked it up.

He stared at it suspiciously. "Whatever happened, I'm going to figure it out."
