The scene begins with a flashback to when Ruby first met Jessie in 2010. Jessie thought Ruby was a temp and immediately went at her with pies and gunge. When Ruby found out she sacked Jessie, but having got her messy revenge she eventually relented. But she has never forgotten or forgiven. In this episode Jessie receives a voicemail from Kitten and when she returns it, Kitten (offscreen) warns her Ruby is on her way to see her. Ruby arrives and says she has heard Jessie gives 'the treatment' with no good reason. Jessie explains she thinks it helps the girls focus, so Ruby suggests she will give Jessie a quiz. If she gets any questions wrong she gets pied. This will see if the treatment brings focus. Jessie starts the quiz well, answering all the first questions correctly, and Ruby thinks Jessie may stay completely clean. But then she asks impossible questions 'what colour knickers am I wearing?' 'what is my bra size?' etc, and poor Jessie begins to take multiple pies of different flavours, and even trifle, before being stripped to her bra and knickers. Jessie moans that clearly 5 years on Ruby still hasn't forgiven her.
