Season 2 according to press release:
This season, Vanessa and Ethan form a deeper bond as the group, including Sir Malcolm (Timothy Dalton), Dr. Frankenstein (Harry Treadaway), and Sembene (Danny Sapani), unite to banish the evil forces that threaten to destroy them. Meanwhile, Dorian Gray (Reeve Carney), the Creature (Rory Kinnear) and Brona (Billie Piper) are all waging battles of their own. Patti LuPone will guest star as a mysterious character of great importance in Vanessa’s past. Helen McCrory returns as Evelyn Poole (a.k.a.
