AN: Sorry guys, Depression's a Witch. And for those of you worried this is definitely Dipcifica.

Pacifica knocked on the front door of the Mystery Shack with three loud wraps. Dipper yawned from the living room chair then looked at Mabel laying on the ground with Waddles.

"I'm not getting it. Waddles needs me," she explained as she scratched his 'chinny chin chin.'

Dipper rolled his eyes but knew his sister well enough to know not to even bother trying to fight with her. She'd win. He got up just as Pacifica knocked three more times.

"I'm coming, I'm coming," Dipper yelled scratching at the back of his head.

"Well hurry up. It's cold out here!" Pacifica demanded.

Dipper opened the door for her. "Sorry to keep you waiting, Princess," Dipper said sarcastically taking a bow.

"Thank you, peasant," she smirked.

Dipper rolled his eyes once more moving out of the way to let her in.

"Pacifica! You're early," Mabel exclaimed getting off of the floor to greet her.

"Really? Now you can walk?" Dipper asked.

"Waddles was in need of critical lovin'. He's good now," She said pointing a thumb towards Waddles who was rolling on his back side to side.

Pacifica blinked at the girl, at a loss for words. "Whatever, have you guys heard?" She asked.

"Heard what?" Dipper asked.

"Turns out Creeper Guy has a name."

"Does it matter what his name is? Like you said the guy's a creep," Dipper said.

"It matters because Ian McGruff disappeared last night," Pacifica explained.

"So?" Dipper asked.

"So! Obviously, Stacy succubused him!" Pacifica explained.

"Come on, Pacifica, you can't really think that," Mabel argued.

"Then do you have another explanation for why he would just up and disappear the day after he harassed her?" Pacifica damneded.

"You saw him. He looked terrified of Stacy when he ran off. Maybe he was so scared of her he decided to leave town," Dipper reasoned.

Pacifica lifted a disbelieving brow. "Oh yeah? Then explain this away. Sheriff Blubs said there was nothing taken from his apartment and everything seemed in order except for a Large Pile Of Dust."

"Come on, you can't honestly think Stacy would ever do something like that."

Pacifica crossed her arms. "Dipper, just because she's gorgeous doesn't mean she's innocent or nice," Pacifica yelled.

"Yeah, I know that. I mean you're standing right in front of me. So…" Dipper trailed off his hand motioning up and down her.

Mabel blinked. "Did you just-" Mabel started.

"You think I'm gorgeous?" Pacifica asked with wicked smirk.

"What?! I mean...uh...I. " He scratched the back of his neck. "Yeah, well...you're still the worst," Dipper said brusquely .

Pacifica smiled softly to herself as Mabel marveled at the blooming blush coming to both teenager's faces with a smile of her own.

"Anyways, you said this guy, Ian McGruff, is that even a real name, is missing?" Dipper asked trying to change the subject.

"Yes," Pacifica nodded latching on to the topic as well.

"So, are we just going to ignore what just happened?" Mabel asked indicating between the both of them. "Cause I really wanna talk about what just happened here."

"Shut up, Mabel," Pacifica hissed.

"Hey! You can't tell my sister to shut up, Pacifica," Dipper defended his twin then turned to her. "Mabel, shut up."

"Touchy," Mabel said holding her hands up in mock surrender.

"Can we get to the subject at hand, Mabel," Dipper asked exasperated.

"I'm trying but you two won't let me!"

"The missing creep, Mabel! That is what is important right now."

"So, you're saying we can talk about you're growing UST later?" Mabel asked with a double fingergun.

"I don't even know what that is." Dipper ran a hand down his face.

"It's-" Pacifica placed her hand across Mabel's mouth.

"Not important. What is important is we go over to that Suck and Kill Barbie and make her-"

"It's not nice to call people barbies," a voice from behind Pacifica said. Her eyes widened as she turned around to find Stacy at the still opened front door.

"How about Bite My Ass Barbie then?" Pacifica snarked.

"Look, guys, I didn't do it. I swear. I went home last night, talked to my dad, did my homework, and went to bed. I didn't even know that guy," Stacy explained pleading for them to understand.

"Of course it wasn't you, Stacy. We'd never believe that you'd ever harm anyone-"

"Except for Kevin and Mr. Riegner," Pacifica said.

"You have to believe me. Please, I know how it looks, but I don't know what happened. All I know is that I had nothing to do with it," Stacy begged her gaze fixed on Dipper.

Dipper pushed Pacifica out of the way in order to wrap his arms around Stacy. Stacy buried her face into the crook of his neck. "We believe you. You're too sweet and kind to ever do something like that. Don't worry, we'll figure out who did it. You never know. It might not even be a succubus. There are so many things in Gravity Falls that could have done this." Dipper rubbed her back reassuringly.

"Didn't we have a no touching policy?" Pacifica asked.

"Oh, right, sorry." Stacy let go of him but Dipper did not.

"She's not doing anything to me!" Dipper complained.

"We don't know that for sure…" Mabel said with a wince. "Sorry, Stacy."

"No, I understand." Stacy smiled a small, sad smile.

"I think I would know if my life force was being sucked out guys," Dipper defended as he held onto her tighter. "And she needs me."

"Okay, Crazy, let's just-" Mabel somehow got her arm between them and separated her brother from the succubus.

Dipper fought to get back to Stacy but Mabel held him tight. "Look, since Stacy obviously didn't do this-"

"That's debatable," Pacifica snipped.

Dipper glared at her. She glared back.

Dipper rolled his eyes and then looked back at Stacy. "Don't worry, we can figure this out. We just have to look up other creatures in Gravity Falls that have the ability to turn people into ash."

"And that creature just happens to attack the guy that was creeping on her just yesterday? Really?" Pacifica muttered.

"Don't pay attention to her," Dipper assured her.

"How are we going to find that creature? When I was researching succubuses the articles talked about a lot of different creatures who suck life forces. How would we narrow the possibilities down?" Stacy asked.

"That's easy. We just look for the ones specific to Gravity Falls," Dipper explained.

"I didn't see any mention of our town though."

"Well, we won't use the internet. We'll just use the jour-" Mabel covered her brother's mouth.

"Well, Stacy, I'm sorry, but Dipper has a lot of research to do and he can't do it if he's, ya know."

"Under her spell." Pacifica offered.

"Right. So, I'm gonna take him upstairs now. Don't worry. We'll figure this out." She smiled kindly at Stacy. "Come on, Bro-Bro," Mabel said dragging him, hand still over his talking mouth, up the stairs.

Stacy looked down lost.

"Well," Pacifica flipped her hair. "I'm gonna go help them. Bye."

"Should I come over later?" Stacy asked.

"Don't call us. We'll call you. Okay? Bye," she said while she ushered Stacy out of the door and locked it quickly behind her before running upstairs to meet the twins.

"-thing? I can't believe it," Dipper said.

"Well it's not like he knows everything. He didn't know about the leaf blower and the gnomes," Mabel reassured her brother.

"I swear you two get stranger and stranger as the years go on," Pacifica said as she entered their room. "So," she sat down on Mabel's bed. "We're not really going to pretend like Stacy didn't obviously do this, are we?"

"Come, on Pacifica, I thought you said she was your friend," Mabel said.

"And she was, before she started putting people into comas and ashes." She huffed.

"Stacy has shown nothing but fear towards her sucubi nature, I don't think she'd use it on purpose," Dipper defended her.

"Of course you defend your new pretty girlfriend," Pacifica sneered. "She has you completely bewitched. 'We believe you. You're too sweet and kind to ever do something like that.'" She fake gagged.

Dipper narrowed his eyes at her. "I don't understand why I'm the only one who gets so affected by her…"

"Remember how I said Jonathan was my soulmate?" Mabel asked.

Dipper frowned. "Yeah, but you say that about everyone-"

"Well, yeah but this time it's real."

"Mabel, come on, you can't-"

"No, Dipper, I'm serious. Stacy said people who have met their soulmate and admitted their feelings aren't affected by her pull," Mabel explained.

Dipper groaned. "Aw man." He grimaced. "Does that mean I have to repeal Code 24?"

Mabel smiled. "You know it."

"I can't believe-"

"You know what I just realized?" Mabel squealed. "Pacifica never told me who her soulmate was."

"Well, I just assumed that was because she doesn't have a soul…" Dipper offered.

Pacifica glared at Dipper. "Screw you, Dipper. I have a soul."

"I beg to differ-"

"You can't speak to me that way!"

"I think I just did."

"Oh, I should-"

"So, Pacifica," Mabel interrupted the arguing couple. "Who's your soulmate?" At Pacifica's blush Mabel looked at her brother who narrowed his eyes at the blonde.

"Yeah, who's your soulmate?" Dipper asked.

"None of your business," Pacifica said through her teeth.

"Come on, we have to meet him." Dipper indicated between him and Mabel.

"Uh, no. You don't. Why do you even care?"

"What? Me? I don't...I don't care care. I just….look, I need to meet him because….because…. what if he's a bunch of gnomes?" Pacifica's mouth dropped. "That happens, you know! Don't think it doesn't," Dipper defended.

Mabel nodded solemnly . "It's more common than you'd think. Darn gnomes always needing a gnome queen."

"Oh my God, why do I even bother with you two?"

"Pacifica, why don't you just-"

"Pacifica, I know you think it's Stacy." When both Dipper and Pacifica made to interrupt her Mabel put a hand up causing both of their mouths to close. "Think of it this way, by helping us eliminate all the other creatures who could have done this you're painting Dipper into a corner. He can't have any 'what ifs' if we eliminate all the other suspects. And Dipper we both know Stacy didn't do this, we just have to prove it to Pacifica."

"Fine," Pacifica mumbled.

"I guess," Dipper grumped.

"Good then let's get crackin'." Mabel smiled.

Dipper sighed but opened up the journal as both girls sat on either side of him all hoping to prove the other wrong.

"See! There's nothing, and no one else who could have done this," Pacifica preened.

"Well, maybe the author just didn't know about it!" Dipper argued.

"Dipper, you can't just ignore the facts."

"I'm not. Come on. How long have you known Stacy?"

"She was my big buddy in kindergarten," Pacifica answered grudgingly.

"And of all the time you've known her did you ever think her capable of something like this?"

"No, but I didn't think her capable of being a succubus either."

"Just because of what she is doesn't make her evil. You of all people should know that."
"How can you still believe her to be good when all signs point to her being evil?" Pacifica asked in a small voice.

"Because not everything is always what it seems in this town. Because Mabel has faith in her and I have faith in Mabel. Because I think she's really scared and doesn't know what to do. She's fighting with her very nature, Pacifica, the least we can do is give her the benefit of the doubt. Right?"

Pacifica swallowed the lump in her throat, blinked back the tears in her eyes, and nodded. "Okay. But if not, Stacy, Dipper, than who?"

"I don't know, but we're gonna figure it out."
