Mathis and Bond talk at a bar on a plane. Bond is drinking to forget about his relationship with Vesper. Mathis comes along to comfort him.
Despite her Disposable Woman status, Bond seems genuinely angry at Fields' death, wanting it noted that she showed true bravery and abandoning Green in the desert with only a can of oil to drink, likely a reference to how Fields was drowned.
Paired with "Tearjerker', Bond and Camille sincerely bonding over their shared tragedies and realizing that they're too damaged to attempt a real relationship, but genuinely wishing each other well when they part ways. It's ironic that he develops a far more profound relationship with a woman he doesn't sleep with than with the numerous ones that he has bedded throughout the franchise's history.
