"Hey Dipper!"
Dipper smiled when he heard the voice. Jill Cryptogram waved to him. She was the town librarian and Tad Strange's sister, being as normal as he was. (Despite the fact that they never seemed to age.) "Hey Miss Cryptogram."
"I thought I told you years ago to just call me Jill."
He shrugged. "Being polite isn't bad."
She chuckled. Her blonde curls were let down today, pulled back with a hairclip. She wore jeans and a blue sweater, brown boots give her a little bit of height. "It certainly isn't. Got any questions?" She seemed to have an infinite amount of knowledge about Gravity Falls. (He was starting to suspect she might be an oracle.)
"Uh, nope." The two walked into the library together. Jill grabbed the cart of returns. "Actually, yes I do."
"Hm?"
"You know about that demon I told you about?"
He didn't notice Jill pale, her hands trembling. "Y-Yeah?" She slammed a book down harder.
"Well, I've been imagining scenarios about the whole 'extinction of an entire dimension'." Jill nodded, biting her lip. Her nails dug into a cover, tearing holes into the cloth. Dipper went on. "And last night, I had this dream."
"Uh huh."
"There was this guy and this younger woman, I think there were siblings." Dipper went on to describe his dream as she looked over the ruined cover. Finally, he finished. "So, what do you think?"
"I wasn't in town when the whole Weirdmaggedon thing happened, but if he was as powerful as people say," Jill placed the book on the shelf, heading to the next place. "And there was a whole dimension of creatures like him, I imagine that they would be very hard to kill. Like..."
"Cockroaches?"
"Not the word I was looking for, but yes. So maybe that dream was telling you that a few got away."
"That makes sense." Dipper looked down when his phone beeped. "Oh, sorry, gotta go. Stan and Ford are here."
She nodded. "Have a nice day."
He ran out of the library. He didn't notice Jill look up at the triangle window and sigh. Pulling a hair tie out, she pulled her hair back. Once she was done, she got to work. She needed to call Tad later, see if they needed anything from the store.
"William, what are you doing?"
Her knuckles went white.
"Working honey. Wanna play chess?"
She had no time for regrets.
"Sure!"
Amelia's eyes were red at dinner. She started at every sudden noise, Stan and Ford not helping. When Dipper asked her, she claimed that she was practicing wariness. Ford leaned over to whisper in his ear. "Can we talk after dinner?"
"Sure."
When dinner was over, they left Pacifica and Mabel doing dishes and Amelia and Stan watching The Duchess Approves. The door slammed shut after them. "What is it?" Dipper asked.
"So, you're moving into the Shack?"
They walked together, talking about this and that. Dipper felt worry crawl through his stomach the longer they walked. "Grunkle Ford, what's this about?"
The old man sighed. "This is about Amelia." He turned to his nephew. "She may not look it, but she is very, very special. I am worried for her safety, because a number of people will give up everything to have her on their side-" A snarl rang out. The two whirled around to see a tall person, sharp teeth bared. Glowing red eyes glared at them. Behind them, somebody stood there, a hood hiding their features. They were reading from a book, lilac sparks around them.
"Run!" Ford yelled. He pulled out his ray gun and aimed at the reading person. It knocked them off their feet. The hood fell, revealing dark hair. Dipper watched as they looked up. It was a young woman with violet blue eyes. She snarled.
The creature ran forward. Before anyone could react, it slashed Ford across the chest. Dipper let out a yell as the old man hit the pavement hard. A nearby house's porch lights flicked on. Jill ran out, dressed in a nightgown. "What's going on?!"
The woman's eyes widened. "Return!" she yelled. The creature let out one last snarl before dissolving into dust. She grabbed her book before disappearing into lilac flames. Dipper turned his attention away from her and to Ford. The old man was cradled in Jill's lap. "Call a hospital!" she ordered.
He pulled out his phone. Typing 911 in, Dipper checked his uncle's pulse. He didn't expect for his wrist to be grabbed.
"Summoner." Ford rasped. Then he fell back, passed out.
