In the novel Clockwork Princess the author, Cassandra Clare, writes about William Herondale and his best friend, Jem Carstairs. These characters are similar by their protectiveness over a woman named Tessa Gray. This woman is cared for deeply by both men. For example, when wounded in battle, both men worry only about if Tessa is alright. Jem is bedridden, but when he sees Tessa, the first thing he says is, “Are you hurt, my love?” (Clare 54). He completely disregards all of his suffering to focus on her, and so does Will. Will, having many scrapes and wounds, refuses to seek medical attention until he can make sure that Tessa is alright. They are also very different from each other. Everything about them is opposite, from physical appearance
