Everything had happened so fast; Skye's brain was still trying to process. Jacob had climbed out from his supposed grave, and had attempted to kill her. Skye had screamed as Felicia fell back into her arms with the dagger meant for her, sticking out of her chest.
Jacob's life was over now, he knew that Prince Tidas would kill him for sure. Attempting to kidnap Skye gave him that right and authority. And it's what Jacob would've done to someone trying to take what was his. He'd decided he would kill Skye before he met his end.. The prince may take his life, but he would take what Tidas cared for most with him.
