The episode title refers to the Olde English rhyme, "Something Olde, Something New, Something Borrowed, Something Blue, A Sixpence in your Shoe". These are the four items that a bride traditionally adds to her wedding outfit or carries with her as good luck charms on 'the big day'. "Something old" represents continuity; "something new" offers optimism for the future; "something borrowed" symbolizes borrowed happiness; "something blue" stands for purity, love and fidelity and "a sixpence in your shoe" is a wish for good fortune and prosperity, although the final one remains largely a British custom.
