Everything seems to be going great... until we notice that there’s still a third of the book left. That means something bad is about to happen.
It's the day of Jane and Rochester's wedding. It should be the happiest day of Jane's life, but during the church ceremony two men show up claiming that Rochester is already married. Dum dum dummm. Rochester admits that he is married to another woman, but tries to justify his attempt to marry Jane by taking them all to see his wife.
