Chapter 7 of Contagion is another chapter that has a changed point of view. Point of view is provided by the character through whom the narrator focuses events and other characters behaviors. The thoughts of feelings of the point-of-view character (the focalizing character) are the thoughts and feelings the third-person limited narrator reveals.
In Chapter 7, the setting switches to an advertising agency, and the point of view is that of Colleen. The action centers around the conversation Colleen and her very ambitious friend Terese have about when Terese will or won't be promoted to president of the advertising agency she works for:
Colleen said ... "You should be content and do what you are good at: doing great ads."
"Oh come on!" Terese said. "You know we advertising people are never satisfied. Even if I make president I'll probably start eyeing CEO."
Action follows through, in this brief chapter, a presentation, called a "ripomatic," that Colleen shows Terese in the "arena" of the advertising agency where rough presentations are rehearsed and critiqued. This chapter is important because of Colleen and Terese's connection to developing the advertising for National Health hospital, the local competitor against Manhattan General, the unfortunate hospital where the plague broke out.
