Last week fans saw that how Vanessa's guilt overpowered her and took her to the dark side again. The mysterious, evil entity took over her for the second time, making it hard for Sir Malcolm to control her. As the day passed by, she got even more violent and unruly. She even attacked the priest as he attempted to eliminate the demon from her body through exorcism and failed him in his endeavour. Later, Ethan performed exorcism for one more time and successfully cured her from the pain.

At the end, Vanessa got back to her normal self and claimed that she now knows about Mina's (Sir Malcolm's daughter) whereabouts.

According to the brief synopsis by TV Guide, "Season 1 ends with Vanessa and Sir Malcolm facing their worst nightmares."

"Grand Guignol" means "The Theatre of the Big Puppet," according to Wikipedia. It was a theatre in Paris that became popular for "naturalistic horror shows." It opened in 1897 and was shut down in 1962 after the management thought that theatre's plays "had been eclipsed" by the real events of Holocaust that took place almost 20 years earlier, according to the Web site.

Is this where Mina is? "Penny Dreadful" Season 1 finale may bring an end to the mystery of missing Mina and answer several lingering questions. But before Vanessa and Sir Malcolm accomplish their mission, they have to get through hell as indicated in the synopsis. Fans can also expect to learn the truth behind the mystery of the murders that took place in "Penny Dreadful" Season 1 premiere. It still remains to be seen, who killed the mother and the daughter in the most devilish manner.
