When the beast that killed that man attacks the FBI agents working the case, he lures Nick there so that he can kill him. When Nick arrives, the beast comes up behind him.

Nick's mother kills the beast and Nick goes to the hospital to give the potion that will stop Juliette's memory loss. He then gets called to investigate the homicide he was just at and has to cover for his mother. Meanwhile, Catherine gets ingredients from Rosalee and makes a potion before calling Capt. Renard to come over. She gives him the potion and says that it will purify him, as only someone pure of heart can wake Juliette. After taking the potion, Capt. Renard kisses Juliette and wakes her up. Nick goes to the hospital to visit her, but the memory loss is already too advanced, and she does not recognize him.
