(I'd like to state that my work is NOT a mistook from any other fan fiction and that this is a completely self ideal) Dark Pinkie (the Pinkie Pie inside Pinkie Pie) decides to kill Rainbow Dash so she will never revert back into normal pinkie from another sonic rain-boom. while caring out her plan to kill Rainbow she comes across a very useful partner in crime that not only tells her they need to kill more than just Rainbow, but turns into her boss that wouldn't think twice about snapping her neck
