 * -Leah Clearwater and Jacob Black on Seth

Seth Clearwater is a member of Jacob Black's renegade shape-shifter pack and is introduced in New Moon as Leah's younger brother and a young member of the La Push werewolf (shape-shifter) pack. Aside from Jacob Black, he is the most developed werewolf in the Twilight Saga.

History
Seth changed earlier in his life than the other werewolves, as he changed around the same time as his sister Leah Clearwater, the only known female werewolf in the series. His transformation, along with his sister's, helped Leah learn why Sam was able to ignore his love for her and move on the her cousin Emily, although she is still bitter about it. On a sadder note, his father had a heart attack when he had just turned teenager, and consequently died.

Eclipse
Seth's major roles happen predominantly in Eclipse and Breaking Dawn. In Eclipse, Seth goes with Jacob, Bella and Edward to serve as a connection between the werewolf pack and the small camp, and fights alongside Edward against Victoria and Riley. He could not, however, claim the single-handed defeat of Riley, as Edward had to intervene when Riley was distracted by Bella, who thought Seth was wounded whilst he was doing a very realistic feint.

Breaking Dawn
By the beginning of Breaking Dawn, Seth and Edward have become good friends in the aftermath of the battle with Victoria and Riley. He also respects the Cullens a lot more than any other member of the pack. Bella enjoys talking to him, which she tells Jacob when he asks why she keeps calling Seth wanting to know where Jacob was when he disappeared.

Seth leaves Sam's pack to become Jacob's Alpha's Second in his renegade pack after Sam decides to kill Bella and the half-vampire child she carries as it posed a risk to the werewolves and the Forks community. Jacob calls Seth a "Happy little punk." Edward has told Jacob that he is lucky to have a connection to Seth's mind, which Jacob agrees to. The fued between the two packs is resolved when Jacob imprints on Edward and Bella's daughter Renesmee.

Seth, along with all the La Push wolves, stands with the Cullens when the Volturi arrive to destroy them.
