 An early version of the film focused on Joy and Fear getting lost together, as it seemed to be the most humorous choice. By July 2012, the project was set for an evaluation screening with other Pixar filmmakers. Docter gradually began to feel that the story was not working, which led to fears that he might be fired. He took a long walk at his home one Sunday, in which he began to consider himself a failure, his previous successes "flukes", and a general sense that he should resign from the film. While pondering what he would miss about Pixar, he concluded that he would miss his coworkers and friends most of all. He soon reached a breakthrough: that emotions are meant to connect people together, and that relationships are the most important things in life. He decided to replace Fear with Sadness, which he felt is crucial to renewal. He met with Rivera and Del Carmen that night to explain his change of plans, and to his surprise, they reacted positively to it. At the screening, he informed his superiors that new plans for the film were in order. Although a "scary moment", the film remained in production.
