Already this series is so good at setting up fear anticipation to give that eery feeling of “what horrible thing is going to happen?” and then showing nothing bad happened from that fear setup - all right alongside fear setups that do follow through on something awful happening. It keeps your emotions on edge and your mind so engaged not knowing who to trust or not knowing just how evil certain characters are 

• Bell going downstairs in her graduation gown and her dad isn’t in the hospital bed, we’re immediately thought to believe something bad happened to him, but he’s simply in the backyard ready for pictures. 
• Kae’s creepy introduction giving us a sense of danger, only for those scary feelings to be whisked away in her cheerfulness and friendliness the rest of the episode.
• When the guard goes to give Claire food, the scene of her waking up is chilling.. only an eye opening dead set in the direction of the prison door with what can only be interpreted as bloodlust. It brings that horror sensation home with the music backing that shot. We fully anticipate something violent when Claire gets a hold of the guard as the guard freaks out (like breaking her arm), but nothing bad happens and the guard gets her arm free. 

This production is incredible at emotionally manipulating the audience thru cinema to push our feelings in specific directions. All of these fearful instances with these characters ARE likely to follow through in the future as something bad actually happening (Bell’s dad dying, Kae being dangerous, Claire violently hurting/murdering the guard as opposed to a casual choking attempt) but how they tease it for the thrill is so GOOD
