Not as dramatic as I feared, but that did sober up the two of them real good. Interestingly, it was never explained why Gimli even stripped down to what's basically her undies, not even as a follow up to a joke about cursedtoolsexual Gaile being immune to seduction because he's only attracted to cursed tools.
Maybe I'll just be thankful he didn't reject the quest in the end saying he can't do it or anything. He did try to foist it as a job for heroes, but Gimli told it to him straight. It had to be him.
