Coda has kept a secret about himself and about her that he didn't time right and didn't tell her in time before it was too late. The wolf awakens inside of her and she gets herself and Coda caught by hunters who want to kill her and her brother for her family's history due to a secret Coda forgot to mention when explaining to Brook who she truly is, and not just a normal wolf-shifter. Brook recognizes an "old friend," but Coda knows him for something different.
