This question contains spoilers… (view spoiler)[Did Ron and Ibrahim cause Bernard to commit suicide?
They meet Bernard on the bench and talk about someone buried there "that should not be there". They are asking about the skeleton in the grave, but Bernard thinks they are asking about his wifes ashes (coincidence). Bernard then commits suicide that night.

Why did Joyce just brush past her friends accusing Bernard and him committing suicide? Am I crazy?? (hide spoiler)]
