Cora Hale survived the Alpha Pack’s attack and left Beacon Hills.
Cora Hale, a character from the television series “Teen Wolf,” is Derek Hale’s younger sister. She was presumed dead after the Hale house fire, which was orchestrated by Kate Argent and took the lives of most of their family. However, it was later revealed that Cora had survived the fire and had been living in South America, believing she was the only surviving member of her family.
Cora returned to Beacon Hills during the third season after learning that Derek was alive. She became involved in the conflict with the Alpha Pack, a group of Alpha werewolves who were targeting Derek and his pack. Cora herself was severely injured during a confrontation with the Alphas, but with the help of her brother and the rest of the Beacon Hills supernatural community, she recovered.
After the Alpha Pack’s threat was neutralized, Cora decided to leave Beacon Hills again. She chose to return to South America, feeling that she needed to find her own way in the world and not wanting to be caught up in the ongoing supernatural struggles of the town. Her departure was amicable, and she left with the understanding that she could always return to her brother and friends if she needed to. Cora’s current whereabouts and activities after leaving Beacon Hills are not detailed in the show, leaving her fate open to interpretation by the fans.
