So, we drew this scene up to just be a scene where Scarlett would pie Colleen. The two play rock-paper-scissors, and the loser of every round gets a pie in the face. Remarkably, every round Scarlett wins! However, at the end of the scene, Colleen decided to take matters into her own hands, and surprise attack Scarlett with the last pie! An all out piefight ensues, poor Scarlett ending up messier than she intended to be going into the scene (this piefight was 100% natural and not part of the script).
