Plan

At the Mystery Shack, the twins came up with a plan. During the day, they would go to your house and knock on your window. You would go to your window and look out. Then they would bust you out. Fulproof right? Suuuuree....... But they didn't realize this at the time. So, they went to bed and waited until morning to go and get you.
"Mabel, Mabel wake up!" Dipper shouted and shook his sister.
"Ahh,Dipper what the heck!" Mabel shouted as she fell off the bed and landed hard on the floor.
" Sorry, but it's time for the plan." he said as he gathered a water bottle and his journal. Mabel got dressed and they both headed toward your house. They tapped on your window, but didn't realize it was the wrong house. Gideon appeared and saw them and smiled. Before they had time to run, he had caught them and had thrown them into a hidden room in the house. He locked the door and the twins heard him laugh, and (y/n) had no idea they were even there. They tried so hard to escape, but it was useless.
"HELP! WE'RE LOCKED IN!!!!!!!!!!" Mabel yelled.
"Mabel, it's useless, we've been yelling for hours." suddenly there was a noise. Gideon walked in and talked.
"Hello friends, didn't think I'd be seeing you today. But I have a surprize for you." he said and strapped them both to a table.
"What are you gonna do to us?!" Dipper asked alarmed.
"Oh, nothing much." he said and laughed. Then, he left not saying another word.
