|“|| Lydia: "Anyone else think we might be doing more harm than good?"|
Scott: "We're trying to keep a father from killing his own daughter."
Isaac: "Actually... we're trying to keep a guy from killing a coyote who is actually his daughter... who we don't know how to change back from a coyote to his daughter."
Stiles: "Again with the not helping."
Scott and his friends attempt to track down the Werecoyote Malia Tate with the intention of changing her back to her human form before her father inadvertently kills her, believing her to be the coyote who killed his wife and daughters. Isaac accidentally steps on a coyote trap and gets his ankle caught in it, while Stiles saves Lydia, who made the same mistake as Isaac, from another trap. Allison uses a tranquilizer dart to sedate Malia's father before he can shoot her. Scott tracks down Malia and embraces his Alpha powers in order to transform Malia back into a human with an Alpha roar, which also gives Isaac the strength to break the trap on his leg. Sheriff Stilinski then reunites Malia with her father. just as Stiles discovers that he has regained the ability to read. Meanwhile, Peter and Derek are freed from their captors by an unlikely ally, Braeden, who reveals that she was hired to free them by Deucalion. At the Nemeton, someone releases a swarm of fireflies that morph into three mysterious figures.
