Mermando sobbed as the twins and Bill vanished before his eyes. All of this was his fault, all he wanted was to see Mabel again, but here's what he got.

As he sobbed, he felt droplets of water dropping on him, he looked up, and saw that it was raining. He sighed, he knew he'd have to bring the news to their family, but how? How can you tell someone that two people of your family has been kidnapped and it's all your fault? Mermando stepped out of the water, his tail separating into legs again, and he was still wearing shorts.

He walked sadly over to the shack, knocking on the door.

"Hello?" Kristian came in, answering the door seeing not her twins like she'd hoped, but a young Hispanic boy, about the same age as them.

"Um, hola, I'm Mermando, I.. I have something to tell you..."

He came in and told them everything, even about the marriage and the deal with Bill Cipher. Kristian's eyes widened and started hyperventilating, "my babies... Kidnapped... In the hands of that... That... MONSTER!" She then burst into tears, "my babies!" Grunkle Stan and Grandpa Stanley (Er... Let's just leave this fic as an AU, ok?) tried to think of something that could undo this, Pacifica was with the twins' mother, sobbing just as much as she was. The twins were the reason Pacifica changed her old ways, Mabel became her best friend and Dipper became her boyfriend. Now, they were kidnapped. And she couldn't help but feel her heart break in two.

Mermando just watched sadly while the group was trying their best to comprehend this tragedy. Being kidnapped by someone is one thing, being kidnapped by Bill Cipher is another, they could be in between dimensions somehow! And even if they brought them back somehow, they could be brainwashed into following their father's footsteps.

Then, out of the blue, Stanley started to speak. "Attention! Everyone!... I've decided to do a search party for the twins, it will be in the forest, even though Bill may have taken them to another dimension, I can't risk being stuck there and never returning. We will start looking for them in the morning, Stan has decided to take care of my daughter while I search for the twins, Pacifica, Mermando, you coming with me?" Stanley asked, looking over at the blonde and the former merman.

"I'll go..." Pacifica said softly while wiping her eyes with a tissue. Mermando just followed a moment of silence, then finally answered. "Yes... Because it's all my fault this had happened, I should be the one to blame..."

"Kid, this isn't your fault," Stanley protested, "it's Bill's fault, now, let's just get some rest to ease this..." And then the group got ready and then went asleep.

...

Dipper woke up with his head pounding and his sister laying beside him, "what.. What happened?" He groaned as his sister started to wake up. "Ugh..." Mabel's head was pounding too. The two then finally got the strength to stand up when a triangle appeared.

"Bill, why are we here?" Dipper questioned, glaring at the floating triangle. Bill gasped, "that's no way to talk to your father!" Dipper groaned, "'father', why are we here?"

"That's better!" Bill shouted with glee. "Well, since my children are here, I suppose I'll explain why. You see, I was hoping to get you kids to realize the fun of being a dream demon! Don't worry, I won't TURN you into one, but I will make you itty-bitty brains realize the truth of it all, you are MY children, so, you have powers that you didn't even realize you had yet."

"So you're saying we have powers?!" Mabel exclaimed, "and we didn't realize we had them until now?" Dipper continued, Bill nodded (which was very hard to tell if he nodded or jumped considering he only has a triangle for a body) "Of course! Now stay here and be good, also, don't even think about trying to escape. You're in between dimensions so it's not like you can find a way out anyways. Good bye!" And with that, Bill disappeared.

"Mabel, what are we going to do? If it wasn't for your damn boyfriend we wouldn't have-" Dipper was cut off by his sister glaring, "oh, so it's his fault huh? All he was trying to do was see me again!"

"Yeah but that cost us being under a dream demon's house and following his orders! Can you ever stop thinking about anyone besides yourself for once?" The words hit Mabel like a hammer, her eyes widened, "I'm selfish? I'M SELFISH? Whenever our parents were fighting, while you were blocking it out yourself, did you even consider, 'hey, I need to comfort Mabel' and did you even consider why I was in a boy crazy phase? Because every girl has the chance to get a romance, everyone but me. I'm too... Different for anyone's tastes!" She then broke down, crying, leaving Dipper absolutely speechless as to what his sister had said.

I'm actually in the middle of writing a fic as to why Mabel is so boy crazy XD
