If one of my supposed best friends tricked me into eating one of my family after all I’ve done for them. I don’t think I would keep a lid on it.
I can only imagine how the Apples are taking this news. At this point in the story Pinkie has broken the trust of basically everyone around her. There is no atonement she can take to make this better, and I only hope she gets put down like the rabid dog she is.
