My biggest reason for sussing WF was that his reasoning seemed a bit contrived. I'll respond to his block of text, and maybe he can clear things up. Given that Mharman and Austin may both be innocent, this will read a bit weird, but here goes.
I don't think he'd be willing to push back that hard on WyIted's misclaim if he was just guessing she wasn't in the game
I don't really get this. If Austin had a fake claim and knew Maya wasn't in the game, he has no choice but to push back because otherwise he gets lynched. Also, a dreamer role doesn't really fit the theme even if it fits that character. I'm also not sure Casey would put both Mia and Maya in the game because it's confusing, but who knows.
My gutread on Austin, like it has been since DP1, is that he's town in spite of all the weirdness with his claim then and even the OMGUS - honestly, I just don't think Austin would respond this way to being sussed.
WF relies on a lot of instinct here, which seems like it would be easy for him to lie about if he was scum. I wouldn't expect a player as calculated as whiteflame to base this much of his decision on a gut feeling, especially when Austin has made mistakes before as scum.
Mharman's claim comes as awfully convenient given the circumstances
This is an odd way of looking at it, because it seems mostly like a chicken-egg issue. Mharman's doctor role seems convenient because it fits Luna's results. Maybe it fits those results because Mharman is in fact a doctor. Given that scum targeted JB, they could have targeted anyone, and Mharman knew he had a power role. Waiting to claim with a power role is just a smart move. Mharman's actions make sense from his perspective. Also, if Mharman was scum, there's a >50% chance he would have visited me or JoeBob or Luna.
Also, we have no other protective role claims. Maybe that's convenient, but it's not something Mharman can control. Phoenix is almost certainly in the game.
Overall, WF is focusing more on behavior than I would like, when the mechanics of the situation come pretty close to confirming Mharman.
