After meeting Q's successor, Bond says "You're not leaving any time soon... are you?" It's subtle, but you can tell that Bond is saddened by Q's impending retirement.
And then you remember the scene was designed as a real-life sendoff for Desmond Llewelyn, who had played the character for thirty-six years, almost the entire run of the series up to that point.
His last words in the scene plus the way he leaves by secret elevator deserve an honorable mention.
Q: I've always tried to teach you two things. First, never let them see you bleed.
Bond: And the second?
Q: Always have an escape plan.
It's twisted, but there's a decidedly WAFFy quality to Renard and Elektra's scenes together. It's fairly easy to forget you're watching a spy flick rather than a romantic dramedy, and that the two people onscreen are brutal terrorists whose relationship is seriously screwed up on almost every level.
Valentin Zukosky is willing to use his last breath bullet to break Bond out of his restraints and sacrifice his chance at getting revenge on Elektra King
