Finally, how does this pertain to DoctorIndigo? Well, you see, with no alignment cop in the game, or at least no dedicated one, why does a Miller exist? It's conventionally "Bastard" to include a Miller in a game where there is no Cop, because it's a role that affects another. Watchers/Trackers can be affected by Sanity, and at its core, a Miller reverses the sanity of the investigation that targets it, but this isn't how Drago, and many hosts in fact, handle Miller.
