I could feel it bubbling inside of me, ready to burst at any moment, and it was searing. I had never been angry at them before. They were my family, the most important thing in the world to me, and I could never find it in my heart to be angry with any of them. This was it though. They pushed me until I broke and now they had to deal with the consequences.
"This is anything but Bill's fault, Dipper!"
The heat spread through my body, no longer focusing itself in my chest. It leaked slowly into the bloodstream and traveled to the very tips of my body. Things were losing color but that was the last thing I cared about.
"In fact, it's yours. You could have stopped all of this if you would have gotten your head out of your book for just five minutes and looked, really looked, at everything around you! There were signs. I gave you a million signs and you ignored them. If had just talked to me like a real person and not some clone of yourself you would have noticed I wasn't okay!"
The air around me felt hot. It wasn't the sticky, wet heat that I was accustomed to. It was dry and it held close to my body. The patch on my eye felt wet and, for a second, I thought I was crying. It would have been the right response. I was always with him, always talking and following, but he never saw me. I was invisible to him when he was the only one who should have seen me.
"Stan Pines, you chose to prioritize fixing that… That machine instead of taking care of the people you were supposed to care about the most. I don't care why you did it. You don't take on a responsibility if you're going to just ignore it. This is your fault too!"
The heat started to burn but it didn't hurt. It almost tickled in a way, sending my head whirling and making it hard to concentrate on the ground. It felt like I wasn't standing anymore, rather that I was floating. Something poured out from under the eyepatch. It was thick and slow, hot and smooth. It was most definitely not tears.
"…But you. Oh, Mabel, I could never be angry with you. I can't even blame you."
From the corner of my eye I could see her clearly as the blue flames burst forth from my hands and wrapped up around my arms. My voice was sweet but distorted and getting more unintelligible by the second.
"How could you have ever noticed when you were so wrapped up in your own head that you wouldn't even help your own brother?"
