Continuity mistake: When Nica, Kyle, and Glenda are at the hotel, Nica asks if Kyle thinks Andy is still alive, to which Kyle replies "I know he is". Glenda goes from having their hands in front of them holding the coffee, to up by their face as though they just took a sip between cuts.
Continuity mistake: When Nadine falls onto the statue and dies, the blood spatter on the statue's face is somewhat different the second time we see it. Some areas have more blood, some areas have less.
Continuity mistake: When Glenda points the gun at Kyle, their left hand goes from holding their right wrist to holding their right hand between cuts.
Continuity mistake: When Devon and Lexy bring Andy into the school, Father Bryce is talking to Sister Catherine about how he's not sure bringing someone he doesn't know into the church is a good idea. The direction Devon is facing changes between shots at one point.

Continuity mistake: At the beginning of the episode, when Andy demands to know where Chucky is, he grabs the chest area of Devon's shirt. When it cuts, he's suddenly holding his arm.
