This episode focuses heavily on Dani's backstory and gives insight into Edmund, aka the Man in the Mirror. During the story, Edmund's ghost makes several appearances behind Dani (7:28 and 35:32) when she looks into mirrors, most notably during the wake when she sees him place his hand on her shoulder (36:04), sending her into a fit of tears.
14:02 — Dani sees Peter's ghost lingering outside the house and chases after it.
28:35 — Edmund is hit and killed by a car, and Dani screams as she runs out of the car to check on him. His twitching hand is a mirror image of the one Dani saw on her bed in the last episode.
Later on, Dani is unable to sleep and leaves her room at night against Flora's wishes to make herself some tea and snack on a few cookies. Flora awakens to see Dani's doll out of bed in her dollhouse and alerts Miles. Together, the siblings race downstairs to distract Dani while the Lady of the Lake makes her rounds across the foyer (46:12), knowing that Dani will not survive if she enters the Lady's path.
