I still believe you vs Fuji was TvS. I think Fuji is town now and logically you're my scum read.
To go deeper with it, I have not been feeling the town Usopp that I've come to know. You lack your usual pushiness. You pushed for Fuji but dropped it after Zem pointed out how you both could be buddies fabricating the whole thing. Afterward, you haven't done much. Only thing I saw you did was engaging in the Everyone vs Fuji interaction that was going on earlier when he got angry and then you followed Dest on Misty. Lastly, what I find to be very concerning is how when you're town, you tend to be the center of attention as everyone is suspecting you for some reason or another. For example, Test ToS 2. But when you're scum, you're not that focused on and skate to the end of the game without any heavy suspicion your way. So far this day phase, you've been matching the latter a lot more than the former.
