During the Introduction The Doubter plays the role of supporter and friend.
During the Conflict stage, they are sympathetic to you and will work to heal and protect you.
When the Suspense leg starts and they realise how much you are going to risk to regain what you have lost the actively oppose your decision and try to force you onto the safest path.
The Doubter plays little to no part in the Climax.
During the Resolution the Doubter acts as a voice for change. Despite reclaiming your hearts desire, they feel the price was too high and urge you to take a different path.
The Doubter’s role in the conclusion can vary wildly depending on whether you took their advice and how much you resent the doubt.
