Well, if Orbo's confirming the shot was legit then Rake either made a phenomenal jump in logic (even for Rake) to conclude that a failed shot = his target must be scum, or Orbo's covering for Rake and they are scum.
It's possible that FML and Gheb are scum mates and FML intended to get others to follow his logic to lynch Gheb and get him major towncred. This theory seems more plausible considering he claimed that they are a one-shot vig, meaning we will have no way in the future to verify their claim now that their shot has been used, and the fact that Gheb was already a slot that was being heavily looked at. It's possible Rake decided Gheb was likely to get lynched and wanted to try to distance and take credit for the lynch so they would look better on Gheb's scumflip.
I can't see why Rake would pull this as scum on town Gheb, especially considering FML wasn't in any danger and Gheb was already on the chopping block. If the goal was to get a mislynch on town Gheb, there was no reason to go out into the spotlight with a fake vig claim because a lynch on Gheb was probably already attainable.
No matter what the case is, we will never be able to verify FML's claim because, whether it's true or not, they are not going to be able to take any more shots since they claimed to be a one-shot vig.
So it's either they're town and Rake went actually full raketard, or FML and Gheb are scum mates. Even if it's the former, Gheb can still easily be scum (but not because he survived the shot, lol), so IMO we should still be lynching Gheb. Then if he flips scum we can look at FML.
Vote: Gheb
