"Ace's initial embrace of her Cheetah instincts by running off with Karra (beat_64bebf87a49a0d96) directly contrasts with her moment of self-reflection by the pond, where she notices her 'yellow eyes' and expresses a desire to return to the Doctor (beat_d9e747f394602952). This shows her internal conflict and gradual awareness of her transformation."
