Chapter 12
Dipper staggered back in shock. He had forgotten to get his book back from Mori. That was bad. Really, really bad. But there was something on the next page of the notepad.
I sent someone to help you so you don't die along the way.
...
"Leave me alone!" Mabel yelled. Dipper was really grilling into her that night.
"Do you like to go shopping? And... have you... by any chance... been shopping today? And did the store you go to, like, only have plastic bags? Or something?" Dipper inquired.
"No!" Mabel exclaimed. "I didn't go shopping today!"
"Or... what about...-"
"Stop it! Can't I have just a little bit of privacy?" Mabel pleaded grumpily.
Dipper sighed. He'd been too obvious. But that was okay, right? He was just trying to look out for his sister.
...
Clink. Clink clink.
Dipper froze.
Was that rain?
Clink.
No. It wasn't. Dipper felt certain it was Mabel. She was obviously putting her plan into action since he was asleep. He had to see her. Had to know what she was doing. He pretended to sleepily roll over to the other side, then opened his right eye to squint just in time to see his sister open her cloth bag. She pulled the plastic bag out and dumped its contents on her bed. A bottle. A tube. A needle. Dipper felt the air suck out of his lungs. Mabel was on drugs.
