Ella and Eliot in the Earlier ARG
The earlier ARG includes Eliot & Ella cartoons and treats the pair as central mascot characters. Those cartoon appearances belong to the ARG, while the stairs choice described above concerns the full game's late route. Keep those contexts separate when comparing their mascot roles with Ella's advice to Tolie.
Ella's friendship with Eliot is explicit in their character introduction. Ideas about what she represents are interpretations unless a scene or diary states them directly. When discussing her role, distinguish her stated friendship and spoken route advice from your reading of their deeper meaning.
