I read somewhere that if you betray Lady Grey and become the mayor yourself, she will ask to marry you still. Is this true?
Whan you find the letter from her sister she will come into the basement and ask you to give her the letter and marry her or say no and become mayor and never see her again. That is a fast way to skip all the junk you have to do to marry her if you like and if you do it that way she wont give you any lip.
