Deucalion

Deucalion is a new character in Season 3 of Teen Wolf and is played Gideon Emery.

Deucalion speaks with a British accent. He is blind, wears dark glasses and carries a cane with a spear tip concealed beneath the red tip at the bottom.

According to Gerard, Deucalion had past contact with the Argent family. In 1977 he was already an Alpha and apparently bit Alexander Argent.

Deucalion also quoted something Chris Argent said back during the Season 2 episode Frenemy.

Season 3

We learn that Deucalion captured and held Boyd, Erica and Cora in a bank vault lined with Hecatolite depriving them of moonlight for four months and turning them vicious. He enlists Ms. Morrell to create a Mountain Ash barrier once Scott and Derek have broken into the vault, trapping them inside. (read more...)

Deucalion explains to Derek how he accidentally discovered that killing one of his Betas allowed him to absorb their power. Once he became blind, one of his Betas felt he was no longer able to lead so he tried to kill him and take control. Deucalion bested him, killed him, and found that he became faster and stronger because of it. (read more...)

At an abandoned mall he and his pack attack Derek's and Scott. He nearly forces Derek to kill Boyd until Allison shoots flash bolts to temporarily blind his pack. Later, at Dr. Deaton's, he kills the badly injured Ennis even though he is expected to make a full recovery. (read more...)

In the motel, Scott hallucinates that Deucalion is standing outside with his mother. Deucalion states that Derek is dead and that Scott is the new Alpha. Due to these events, he is coming for Scott and "everyone he loves". In the final moments of the hallucination, Deucalion slashes Melissa's neck with his claws. (read more...)

Deucalion first arrives at the scene of another dead body, when one of the twins whispers something in his ear. Later, Deucalion waits in the music room of Beacon Hills High School for Scott. He promises Scott that someone would die that night. Deucalion then offers information regarding Deaton's whereabouts only if Scott could take his cane from him. After multiple unsuccessful attempts, he cuts Scott's shoulder with the spear tip on the end. Despite the failure, Deucalion relays an important clue on how to find Deaton. (read more...)
