She tells him that he needs to commit a murder. But without saying anything, Subaru leaves and has a childhood flashback about his mother locked up in cell. Subaru than gives Yui a silver knife given to him by his mother that can kill the vampires if stabbed through their hearts but Yui asks him why he gave it to her. When he turns around to look at her face, he remembers his mother's face. Yui then asks him if he knows anything about her or her father as she was told that she was offered as sacrifice by the church but Subaru tells her that he knows nothing. He asks her why she is still here because she wasted a rare opportunity to escape. She goes to her room and starts packing her suitcase but she stops when she looks at her fathers diary and the picture and she tells herself that she can't leave without finding the truth so she goes back to Subaru who is sitting by the window. Subaru tells her to go now because she has a chance now. Yui then walks toward him and leans into his chest and asks him what choice she has. Subaru tells her she will definitely die if she stayed here any longer. Subaru meets Yui when she comes back from sacrificial bridal room. After he disappears, Subaru turns around to look at Yui (who just returned after her encounter with Kanato in the graveyard and is oblivious of her surroundings) and wonders what Richter meant by that statement. Richter then disappears and says 'the awakening will manifest'. Subaru then gets angry and demands for him to leave. Richter, instead of answering, asks Subaru why he won't call him uncle. Subaru sees Richter outside the residence and asks him why he is here.

When Shu leaves the table, everyone including Subaru leaves as well. Subaru is sitting next to Reiji at the dinner table. Subaru is seen sitting in the limousine next to Reiji. When she says 'I am nobody's prey', Subaru just tells her that if she tries to escape, she will die. Later in the episode, when Yui runs to the abandoned room and the Sakamaki brothers find her, Subaru slams the bookcase and tells Yui to stop making excuses. When Yui asks what he is doing, he answers her by breaking her phone and tells her to get lost.

After sometime, he snatches Yui's cell phone from Ayato. This further enraged him and he tells her to answer him first, punching the wall hard to try and intimidate her, which also results in the destruction of the wall. Instead of answering, Yui asks him about how he got in the room.

Subaru then angrily questions Yui since she disturbed his sleep. He tells everyone that he was sleeping, but woke up due to Yui's smell. Subaru appears out of no where when everyone is asking Yui who she is.
