Octopussy recalling her father's death, preferring to kill himself rather than face dishonour.
Vijay's death.
Q was the one to find Vijay, and he lived just long enough to tell Q who was responsible for it. Sadly, by the time Bond returns to his friend there's nothing he can do for him, and he quietly covers his body out of respect.
When another character blithely declares "No problem", Bond winces, clearly thinking of Vijay.
The look on Octopussy's face when she confronts Kamal Khan in his palace following his treason speaks volumes on how she feels about being duped and left to die in a nuclear apocalypse.
