Chapter 1, Page 12, Panel 3-5
In Watchmen, Rorschach's inkblot mask changes according to his emotion. In panel 4, Rorschach is thinking about who could be killing the ex-superheroes or why they are being killed and there are two blots in the upper center of his mask, almost like he is furrowing his brow. When his emotions become more and more intense, his mask will change more rapidly. The authors' decision to have Rorschach's mask change with emotion lets the reader know more about Rorschach than a lot of his dialogue. Rorschach is a very cold fellow and doesn't reveal much about himself, but his mask reveals much more about his character.
