Karmon Hale is the only Human Survivor of the fire that decimated his family and home from the Argent family. He helped Cora escape too, but few hours after running from the Argents, they ran into Deucalion and his Pack of Alphas. Cora, ready to protect her brother, told him to run, and he did, but felt like he left her for dead.
A few years have past, and Karmon is now living in Crystal Waters because the Supernatural inhabitants reminds him of his thought-to-be dead family, but little does Karmon know that Cora, Derek, and Peter are alive and are in Crystal Waters. Karmon one day goes to school, and bumps into Scott McCall, who finds out that Karmon is Derek's younger brother, and tells him that He's alive, but doesn't know that he's in town until he runs into both of them.
