I don't really give him points for Tweet as I've already said, he gets some for it but it's still fairly possible it's a bus, as it came later and there's a decent chance the execute had already been submitted by then. Claim is pretty meh, very easy to fake so not really much in that influencing me.
Jeffa's post highlighting his earlier play has given me a lot of doubt, as I've not read pretty much anything that happened before I came in yesterday so I've not really seen much first hand. But the swap from Jeffa lying to Tweet being the one lying near end of day doesn't look good, nor does the sort of trying to get credit here at the later part here, and saying he's been the best town player by far and away while everyone is voting him for doing nothing isn't a great look. Does get points for softing the gravedigger role earlier, but it's still possible he just sorted his claim early.
I'd probably be fine at lynching him at this point as I don't see a whole lot of reason that it would be a bad idea. That said, I'd get other stuff first as we've still got a lot of time
