We should have an Escort, as two Consorts seems unlikely, and there are too many role blocked claims to just be Drug Dealers/Blackmailers.
Escorts learn information.
Doctor learns information.
Journalist (investigative?) is a route to reads and information
Bus Driver can deflect and impact the game.
We actually did have a Detective, he just died. I should clarify I believe we have no more remaining Investigative roles, as he was clearly in game.
Architect, while the role card was confusing, forces discussion and possibly claims.

We have non-investigative investigative roles with us.
