however, if i entertain the thought of aqua being town, i then have to explain why his and my role both exist. i can think of two ways we would both exist though.
the first is that 1) there are scum deal-makers, 2) the anti-town-sided consequences of scum's deals are such that if i cancel the deal the next night, that action helps town, and 3) the anti-town consequences of town sinner's deals are such that cancelling the deal the next night is pointless because the damage is already done. this would mean that my role is ineffective if i target townies, and only effective if i target scum deal-makers - and aqua's role would be the exact opposite, being effective only against townies, and not against scum. this would be reason for us both to exist - we both hit blind spots of each other.
the second is that, for balance purposes, stranger decided that having only 1 town role that could, each night, either stop scum from making a deal OR stop town from being forced into it, wouldnt be town favoured enough for whatever reason (and the reasons would involve what the deals actually do), and wanted town to have a bit more chance against deals, and since having 2 roles able to stop mafia deals seemed too town favoured, she chose instead to make another role who was able to only prevent town sided deals, but was still powerful in its own right due to the mini-cop aspect.
both those scenarios are imo fairly reasonable/realistic and i could easily see one being the case, so coupled with my town read on aqua,
after working through it all in my head, i do think its realistically possible that we both co exist, i dont have enough reason to believe otherwise, and i dont want to lynch based off it.
