A suggestion for mini crewmates, or pets is that if they witness the killer murder the owner, or a player, it will shake or have a visible hint to the presence of the impostor, simply from the trauma. If this suggestion was to be used, there could be a short visual for completing tasks, like a little cheerleader. Although this determines people's superiority, from purchasing a pet, they purchase an advantage to not be sussed. There are pros and cons to my opinion, but I would love a feature of a traumatised pet shaking in the presence of the impostor.
