By the time Creta arrives, Toru cannot distinguish hallucinations from reality. In fact, it is difficult to know whether Creta is responsible for rescuing Toru from the well. After all, if she did help Toru, it’s odd that she wouldn’t stick around to make sure that he’s okay. Also like Mamiya, Toru had to climb out of the well by himself. Symbolically, this represents Toru taking control of his life and overcoming great mental and physical challenges.
