Mabel P.O.V

"What the hell do you mean, Dipper!?" I practically scream, shock influencing my actions.

He rubs the back of his neck and looks down at the floor.

"You can't be serious! Have you forgotten what he's done to us!? He's tried to kill us! He's using you! How could you let him get to you in such a weird way!?"

Dipper continues to look at the floor in shame. It's obvious that this is not the reaction he was hoping for, although I'm not sure why he would think I would have any other reaction.

"What makes you think that being with him is okay!? Did he get in your head!? Are you 'Bipper' again!?"

He finally stands and looks upset.

"No, I'm not 'Bipper'! I'm your brother!" he snaps. "I know that this isn't okay! God, you think I haven't thought about that!? That's all I can think about when I spend time with him! Fucking hell, Mabel! I get that you hate everything about this, and you have every right to, but don't make me feel like some piece of shit, puppet!" he screams, finally losing his cool.

I get up from the bed and clench my fists tightly. He's making me mad. I'm only trying to protect him from the dream demon that will only get him killed.

"What the hell am I supposed to do!? My twin brother is in a relationship with our family's sworn enemy! He's only using you to get back at us! He's going to get you killed and then come for the rest of us! You're just a piece in his game!" I argue, stomping my foot out of frustration.

Dipper turns and kicks his bag against the wall. I'm hitting all of his nerves while trying to convince him that Bill is not good boyfriend material.

"I thought of all people," he says softly, "that you would understand."

His statement leaves a sour taste in my mouth. I'm the person he's closest too. He trusted me with the biggest secret he's ever had and all I'm doing is screaming at him and telling him that it's horrible and wrong.

"Dipper," I say after a few moments, "I want to understand, but this is Bill. If you were with anyone else I would understand, but when it comes to him I just can't bring myself to accept it. He's going to hurt you or get you killed. I don't want to lose you," I explain softly, putting my hand on his shoulder.

He shrugs my hand off and goes to the door. I've upset him by telling him the truth. It's not what he wants to hear.

"Where are you going?"

"It's none of your concern where I'm going. If you don't accept this then go home and leave me alone," he snaps harshly as he leaves the room and slams the door.

I sigh and sit down on the edge of my bed. I hate fighting with Dipper. It's not something we do often.

'I wish he understood what Bill is doing to him. I can't let this go on. I have to protect him.'
