If Rui was really Drunk (or Poisoned) then Spectrier wouldn't know what she'd claim in advance. When she claimed that Hareta/Watt was Scarlet Woman, Spectrier would know that was untrue and vote for Watt anyway.
[[Glastrier's being dramatic, but I honestly stand by voting for Watt. We had no reason to think Rui's intel was wrong yet, and I figured that even if we were wrong, I'd be in the perfect position to clear him after death, and that because of the way voting works in the game and the lack of flips, mechanically-clearing someone after death was waaaay more valuable than not, especially since it'd implicitly give us a three-for-one special with Rui and Hareta.]]
