I understand not wanting scum to know what you were doing but after everyone was getting confused, you should have realized that it'd be much better to clear up that confusion so town doesn't 1. scum read you and 2. cause the actual invest role in the game to be outed. Once whatever tactic you're trying to do causes more damage to town than it does to scum, you have to explain yourself and help minimize the damage. It becomes irrelevant if scum knows what you were doing at that point.
