Let me be honest, the previous episode (3) wasn't that wooow as the whole show trend. But in episode 4 "A Blade of Grass" things returned to its right direction with the astonishing acting by both Eva and Rory. On one hand Eva as the miserable Vanessa who has a very dark past and trying unsuccessfully all the time to not remember it; which leads her to this so called mental ward cell suffering the inhuman therapy methods of the 19th century starting by inducing her to eat up to letting her to sleep without a blanket after a deadly unwanted shower and finally the attempts to open her skull. But she was able to handle all these moments and scenes with her natural beauty even under the terrifying makeup. On the other hand, Rory showed unexpected face of John Clare; and the smooth transition he'd been performing between the good and noble orderly to the completely opposite side as the villain Dracula and Lucifer. All of these scenes were in the enclosed white padded room. Shortly the best episode up to now.
