After two successful seasons, Showtime's Gothic horror thriller Penny Dreadful is returning for season 3 in May. A teaser released by the network reveals that Vanessa's problems are far from over. Fans are expecting a romantic spark between Eva Green and Josh Hartnett's characters in the upcoming season but the teaser suggests otherwise.

In season 2, Vanessa and Ethan formed a deep bond with Sir Malcolm and Dr Frankenstein to fight the evil forces from taking their souls.

In the previous season, Ethan decides to go back to America. The synopsis teases that a new character will be introduced who will have a deep connection with the American man.

Kaetenay, a Native American with a "deep connection with Ethan" will become an ally of Sir Malcolm. The series reinvents the terrifying yet popular characters from fantasy literature who join some original characters in a dark and brutal quest to save souls from demons.

Here is the full synopsis:

Season three includes a wealth of new and returning stars. Tony® Award winner LuPone (American Horror Story), who guest starred last season as the Cut-Wife, returns as a series regular in the new role of Dr. Seward, an American therapist who treats Vanessa with an unconventional new approach. Wes Studi (Hell On Wheels, A Million Ways to Die in the West) is a new series regular starring as Kaetenay, an intense, enigmatic Native American with a deep connection to Ethan (Josh Hartnett) who also becomes an ally to Sir Malcolm (Timothy Dalton).
Guest stars Sarah Greene (Hecate) and Simon Russell Beale (Ferdinand Lyle) return, along with new guest stars Shazad Latif (The Second Best Exotic Marigold Hotel, Spooks) as Dr. Henry Jekyll; Screen Actors Guild® Award nominee Christian Camargo (Dexter, The Hurt Locker) as zoologist Dr. Alexander Sweet; Sam Barnett (2012, Jupiter Ascending) as Dr. Seward's mysterious young secretary; Jessica Barden (The Outcast, Far from the Madding Crowd) as Justine, a young acolyte to Lily (Billie Piper) and Dorian Gray (Reeve Carney); and Perdita Weeks (The Tudors), as Catriona Hartdegan, a scholar with expert knowledge of the supernatural.
