What I think is being lost in translation in me not seeing how she can be scum is that it really doesn't have to do with mechanical evidence or how hedin designed the game. That's a by-product but the real thing is how the information came out. From my perspective, if I were to assume they are scum, they made this fake claim that they revealed before me because melon straight up says they are a hider in passing very early, I remember noticing it like day 2 or 3. They then proceed to argue with me about how the ability works. It's possible scum had already picked up on Fireblend and Fran having the same but different powers by the time we had this argument but even then, I don't see scum risking a weird double claim where you want to say the abilities are different with the same keyword on just one example. If they had known about Zipped as well then sure but it seems very unlikely that Zipped was role copped now since they would have killed off those doctor shots way earlier if they knew.
Like if you want to fake claim, you can just say the ability works the same. I don't see why melon argues with me to their own detriment there because that was speeding ahead to a situation where we lynch both of us. The only reason that didn't happen is because we got more information that made it seem like this was the more plausible situation. A double claim isn't an issue in this game, there have been multiple copies of abilities all over the place, the standing their ground that it was only kind of a double claim is where I see issue. It was suicidal in the moment and literally the only benefit they would have gotten out of it is trading 1:1 with me.
