Among all the 'Hannibal' season 2 excitement of the past week, as NBC released its first spoilery trailer and photos of Bryan Fuller's darkly delicious returning drama, we knew that one casting announcement meant some major villains of Thomas Harris' literary Hannibal Lecter canon would be on their way. To wit, our Margot Verger has been found, courtesy of 'Being Human' star Katharine Isabelle!

As first reported by TVLine (though the post was repeatedly updated to reflect that Margot may end up a love interest for Will, even as the books depict her as a lesbian) Isabelle will first appear for a recurring role in the eighth episode of season 2 as a patient of Hannibal Lecter's, something that in and of itself may debunk Dr. Lecter's public standing, at least as potentially spoiled by the most recent trailer.

In any case, Isabelle's Margot Verger has been described as beautiful and compelling, while having suffered years of abuse at the hands of her serial-killer twin brother Mason, whose casting has yet to be announced. Literary fans will remember that Mason’s sister Margot first appeared in the ‘Hannibal’ novel, taking place some time after the events of Lecter’s incarceration and escape, by which time Margot had undergone stark changes from her initial role as Hannibal’s patient. Cinema icon Gary Oldman brought the character of Mason to life in Ridley Scott‘s 2001 adaptation, albeit grotesquely deformed from his encounters with Hannibal.

Elsewhere, series creator Bryan Fuller has confirmed Raul Esparza’s return to ‘Hannibal’ season 2 as Dr. Frederick Chilton, while ‘X-Files‘ vet Gillian Anderson will reprise her role as Hannibal’s own therapist Dr. Bedelia Du Maurier, as will Eddie Izzard as Dr. Abel Gideon. Along with confirmed season 2 roles for ‘Sex and the City’ vet Cynthia Nixon and ‘Homeland‘ player Martin Donovan. The recent TCA press tour also revealed that ‘LOST‘ star Jeremy Davies and Jonathan Tucker have also joined in unknown roles.

NBC's 'Hannibal' has plenty on its plate for the second season already, but we're excited to see how Bryan Fuller's vision deals with the Mason twins, who never appeared in the literary canon until well after Hannibal had first met them. In the meantime, watch the dreary new trailer again below, and tell us what you want ot see from the February 28 premiere, "Kaiseki!"
