I am on page 43 right now. My read on Usopp is town.
Usopp's worst posts to me are these two where he deflected to someone else while responding to suspicion on him. Deflections are inherently suspicious and a bad thing to do. But I will refrain from suspecting Usopp just for this due to how commonly deflections are done by townies. It's naturally suspicious but not alignment indicative.
This post below from Usopp is very good.
I understand his logic in here perfectly and it makes a lot of sense. This leads me to my reason for town reading Usopp. He is town for his consistent townie progression. He has constantly defended himself and explained everything thrown at him logically in a way that would make sense for a townie to do. Case in point, Mel rescinded her scum read on Usopp after revising him, stating that he's been consistent. On the topic of Usopp throwing out town reads like candy. That's not suspicious for him to do. He's done it as town all the time and truth be told, never as scum. I know I said earlier that he can easily replicate that as scum, but fuck it, I'ma add it to the reasons for why he's town. The way he's playing the game bar for bar matches town Usopp.
Another reason why he's town is how he's defended himself. He was composed at the start, staying cool and collected, responding constructively to everyone who questioned him. He was not flustered. Then he slowly became more frustrating, specifically at Flower and Al as he believed they were coming at him with some bullshit. I agree with that(will explain below). Usopp's defense strikes me more as town defense than a scum defense.
Overall, the reasons to suspect Usopp, to be frank, suck. His "slips" are nonsense. I already explained why Flower's wasn't actually a slip. And really to me, Flower is just coming across as spiteful towards Usopp for him being happy about lynching a town Flower(which is a boost in her favor. Makes me town read her more, but it still wasn't a slip). Al's slip, I don't really understand. I get what Usopp was trying to say. If he, me, and Xlaw are scum but not together then logically, at least 2 of us are indies. What Usopp is saying is that none of us can be buddies together, ergo at least two of us have gotta be indies. That's the logic.
So yeah, Usopp is town. I would also like to really talk about somebody: Odd. That man is yikes all-around. I'll talk about him in a later post after I catch up.
