Kate Argent

Kate Argent is the sister of Chris Argent, aunt of Allison Argent, and the sister-in-law of Mrs. Argent.

Like her brother, she is a hunter. She was introduced in Magic Bullet when she came to stay with the Argents at their new home in Beacon Hills.

She is pushing Allison to learn more about her family and seemingly leading her into the family business of hunting werewolves. In The Tell she gives Allison a silver pendant featuring a wolf. In Heart Monitor, she directs her to the French legend of La Bête du Gévaudan and the connection between the beast in the story and the Argent family. In Lunatic, Kate teaches Allison to use a Taser gun.

While gentle with her niece, Kate seems ruthless as a hunter. She responds without fear when The Alpha attacks her SUV in Magic Bullet grabbing a gun and firing at the first thing that moves. The bullets she fires are tipped with a type of wolfsbane which poisons and nearly kills Derek. During a later confrontation with Derek Hale in The Tell she seems to enjoy taunting and torturing him before trying to kill him. She is constantly pushing Chris Argent to act against The Alpha while her brother urges restraint as they gather more information.

The character's dialog is rife with sexual innuendo. She makes suggestive comments to Derek while torturing him and teases Scott during the family dinner in Magic Bullet. Allison claims to have found and taken a condom from Kate's luggage. She seems to be attracted to Derek.
