I believe Yolanda is so desperate to get the papers signed because the pain of the ensuing divorce has been so much, that she wants it finalized so she can try to move on with the rest of her life. Although they once loved each other, their personalities clashed. Yolanda was a poet, an artist to the core. John was a English businessman with "titles" and all that made up aristocratic stuff to make the rich feel better about themselves. We see this clash come into full view while the both of them observe a Chagall painting. She wants to analyze the meaning behind the work, while John could care-less.

I feel the grandfather's physical suffering could possibly be a symbol of the suffering that Yolanda is emotionally feeling. Her grandfather is dying, and so is her marriage; the love she once had. We've all had our fair share of people come through our lives, but its the ones you love that will always be remembered. Yolanda will remember John forever as well. Just because a love goes sour, doesn't mean it will leave your memory. In fact those are the memories that sting the most. Does any one else find that the grandfather can't remember his mother's death, but He still remembers the love he once had with his own wife to be very ironic?
