As Vick escapes, the mist envelops the bookstore where Alex is reading to Lyla, and the shadow creature appears in front of Lyla, killing her.
The shadow creature then appears in front of Alex, but she escapes, claiming that she fought it off. She later reveals that the creature had in fact spared her for unknown reasons.
