I don't understand the ending of "The Son's Veto" by Thomas Hardy. What happened; who died?

The ending of "The Son's Veto" is veiled in suggestion on
purpose to give the reader a moment of mild horror at the reality of Sophy's situation and of
Randolph's inner traits. The resolution is thus intentionally elusive (though
not ambiguous); Hardy
would be pleased that his technique of suggestion succeeded and readers must do a double-take and
reread the last passage to truly understand what has happened. Let's piece the resolution
together.&llt;/p>

Randolph has made his mother swear before an alter in
his room that she will never "wed Samuel Hobson without his consent." Hardy subtly implies that
many years go by with the line, "Her lameness became more confirmed as time went on." He also
implies that the stress and sorrow of forestalled happiness is wearing her down because she
"would murmur plaintively to herself when nobody was near," saying "Why mayn't I say to Sam that
I'll marry him? Why mayn't I?"

Next, Hardy switches his point of view to "a
middle-aged man [who] was standing at the door of ... a fruitier shop" in a neat suit of black."
Here, the reader doesn't actually know who is spoken of--as Hardy intends--but suspects it must
be Sam. We hope, despite the change in narrator tone, that he is wearing black in front of a
"partly shuttered" window because it is his wedding day and Sophy has finally defied her son's
veto and will marry Sam.

Then Hardy throws us into confusion by
telling that a "funeral procession was seen approaching." What does the funeral mean to Sophy and
Sam? Whose funeral is it? That the man's "eyes were wet" as the funeral past by contradicts our
hope of a marriage between Sam and Sophy--if indeed the man is Sam--still we are not sure of what
is being presented.

Then we learn who is riding on the mourning coach. It is a
newly ordained clergyman: "a young
smooth-shaven priest." He looks "black as a cloud." His black look is aimed directly at the man
with wet eyes in a black suit with his hat in his hands. Then we know--against our wills we
realize--the man standing thus in front of his shuttered shop is Sophy's own Sam. The cold and
hard "priest" with the high collared "waistcoat" is Randolph, from whom his "education had ...
ousted his humanity." The one riding at rest in the funeral carriage is lame Sophy who has died
under Randolph's crippling veto. It is Sophy, Randolph's mother and Sam's love, who has
died.
