Young Luke is drawing pictures with his crayons. The lunchbox he keeps his crayons in is one that features E.T. the Extra-Terrestrial (1982). Featured on the lunchbox is a drawing of a young Henry Thomas. In addition to this, the closing Amblin Entertainment logo features an animated graphic of Elliott and E.T. flying across the moon, giving Henry Thomas three different appearances in this episode.
When Olivia interrupts Steven and Mrs. Dudley's conversation, a face can be seen behind her as she moves through the door frame. It is gone when she turns to leave after inquiring about Luke.
In the first episode, the Lasser Glass from Oculus (2013) can be seen on the wall of Hill House while Nell (Violet McGraw) is dancing through it. Oculus is directed by Mike Flanagan.
Filmed in Atlanta, Georgia.
This is Elizabeth Reaser's second time working with co-star Henry Thomas. The first time was in Ouija: Origin of Evil (2016).
