My MC is experiencing auditory hallucinations from a, currently, friendly voice. Eventually, the voice will become sinister and a different visual hallucination will appear to try and intimidate the MC into doing what she wants. The auditory hallucination knows the visual hallucination by name.

How soon is too soon for the auditory hallucination to drop the name of the visual hallucination? Im considering dropping the name pretty early on into the MC and auditory hallucinations relationship but Im worried itll be too obvious.
