I think Psychic said that after the second mason came out? I think she said something along the line of 'double masons can't be good for town, one must be scum'. So it had nothing to do with knowing the host, but I think just a reaction to there being a second pair of masons.
Does Indigo not get any benefit of the doubt in your eyes for claiming second mason pairing? Is Flower a town read for you here? Obviously you're much more familiar with Poyser games and how he might handle mason pairings, but in my eyes, Flower first coming out with a mason claim and Indigo doing it second, show me some town motivation to be open and honest. I do agree that Indigo hasn't really done anything for posting, though, and my town read of him is solely based on him coming out as the second mason pairing. I'll also admit I've lost track of Flower a bit in this game because of her claim.
