"I found my bike."

"That's cool. Where'd you find it?"

"In my garage."

"What? No way!"

"Yeah."

"Who would steal a bike, then give it back?"

"I'm pretty sure I know who."

"Dipper! Hey, I've been meaning to talk to you!"

Dipper's heart skipped a beat. Wendy wanted to talk to him. Either this meant something really good or really bad, he was sure of it.

"Yeah? What's…"Dipper stopped. Robbie was standing next to Wendy behind the counter…and he was smiling. That meant something really bad. Dipper quickly glanced around the room. They were alone.

"Good news, someone returned Robbie's bike yesterday," Wendy said happily, quite a contrast to the sinking feeling it gave Dipper.

Oh no. Oh no, oh no. oh no.

"They left a note," Robbie said as he handed Dipper a piece of notebook paper. Written in pencil was this text:

Robbie,

Sorry about stealing your bike. We I didn't damage it, so please don't get upset.

Anonymous

Dipper swallowed hard. "Wow, good for you, Robbie," he said, handing back the note.

"Any idea who might have done it?" Robbie asked, his voice hinting at the inevitable.

Wendy laughed, "Robbie seems to think you did it, isn't that crazy?"

Oh man.

"Heh, yeah, crazy."

"Did you do it?" Robbie asked, a smirk playing on his face.

Dead…I'm so dead.

"Well, not exactly," Dipper said slowly, rubbing his arm.

"What?" The smile quickly fell from Wendy's face, "Dipper, did you-?"

"It's a really long and complicated story."
