On the third episode of the sixth season of Heroes, Claire’s new college friend Gretchen is flipping through one of Claire’s books. The front cover isn’t shown, but a glimpse of the back cover can be seen. The book is Clumsy by Jeffrey Brown.
Check out the back of the book that Gretchen is holding in the screenshot. Look familiar? It’s only fitting that Claire owns a copy of this book seeing that her ability is to be able to quickly heal herself from injuries. Clumsy makes an appearance on NBC! w00t!
