They were fighting again.
"You said it was okay for me to hang out with Grunkle Ford!"
Dipper only wanted to be with Grunkle Ford now. He didn't have time for her.
"You can't keep him away from me! I'm his family too!"
She's family too. Why didn't Grunkle Ford care about her?
"Oh, now you care about family? Dipper could have gotten hurt, Stanford!"
Grunkle Stan has been so sullen since Ford came back.
Mabel wanted them to be together. But they fought when they were together. It hurt Mabel when they fought. It hurt so bad. She can't keep it inside. But she can't talk to anyone about it because she'll only make everything worse. So she let her pain out another way.
She grabbed the knife from under her bed. She stole it from the kitchen a while ago when she first started cutting herself. She usually did it when they were fighting. They never paid attention to her when they were fighting. But the cuts she made in her arm couldn't drown out the screaming.
"Why do you care about having company anyway? You don't even wanna be here! I spent thirty years trying to get you back and you've never even thanked me!"
"I'm not thanking you for putting our entire dimension in danger!"
"Sometimes I wish I didn't bring you back."
Mabel made her cuts deeper. Deeper than she's ever done before.
"For the sake of our dimension, I wish that too."
Mabel gasped in pain. She accidentally cut too deep. Now she was bleeding profusely. This had never happened before. It was going to make a mess. She took off her red sweater with the big pink heart. It was one of her favorites. Now, she used it as a rag to wipe the blood. The blood was so thick that the pink heart was no longer visible. It was just a plain, red sweater now. But she didn't care. All her sweaters were good for these days was covering up the scars on her arm.
She made Waddles wait outside when she cut herself. She couldn't make him watch. He usually oinked under the door begging to be let in. Now he was furiously scratching at the door. It was like he instinctually knew his owner was hurt. When she didn't open the door, Waddles knew he had to get one of the other humans to help.
