Continuity mistake: When Astrid and Claire visit Ingrid in prison, two kids are seen running towards them from behind.

However, when it shows the backside of Claire and Ingrid in the next shot, the two kids have already passed all three of them. (01:06:25)
Continuity mistake: When Astrid is talking to Paul, after the prison visit to tell Ingrid she won't be back, her eyebrows are suddenly brown. Allison Lohman had begun to film another movie about a teen with cancer. For this reason, her brow color was darkened.
