'Supernatural' spinoff changes title and completes main cast

Two significant pieces of news about the Supernatural spinoff emerged over the weekend, as the series has now completed its main cast and changed its name.

The show, formerly known as Supernatural: Tribes, is now known as Supernatural: Bloodlines. The spinoff has also cast Melissa Roxburgh in its final series regular role as Violet Durant, "a member of a powerful werewolf pack who hides her true nature because of her forbidden love for family rival David, a shapeshifter," according to TVLine.

This completes the casting, as Danielle Savre (Heroes) and Stephen Martines (Burn Notice, The Closer) were the two most recent additions prior to Roxburgh.

Savre will play Margo, the head of a family of shapeshifters. The character is an "ex-punk rocker-turned-corporate professional who feels threatened only by the return of her prodigal brother David," according to TVLine. Nathaniel Buzolic of The Originals plays David.

Martines will portray Detective Freddie Costa, "a world-weary" cop who acts as a mentor to new hunter Ennis Roth (played by Episodes' Lucien Laviscount) and is also on the payroll of one of the monster families.

The show also cast Sean Faris, who will play Julian Durant, the son in a wealthy family of werewolves who harbors hatred for the shapeshifters of the Hayden family.

Faris currently has a recurring role on Pretty Little Liars as Officer Gabriel Holbrook and has previously ventured into the supernatural genre with a role as vampire Ben on Season 1 of fellow CW series The Vampire Diaries. He has also starred on Reunion and Life As We Know It.

The characters will all appear in the 20^th episode of Supernatural's current ninth season, which will serve as a backdoor pilot for the show.

Tribes has been described as a "sweeping drama about the various mafia-esque monster families that unknowingly-to-humans 'run' the underbelly of Chicago and who are being tracked by a newly-minted Hunter who's trying to stop them and rid Chicago of anything or anyone supernatural."
