The myth, as it's usually told
Narcissus was a young hunter so beautiful that everyone fell for him, and he rejected all of them, Echo included. The goddess Nemesis led him to a still pool, where he fell in love with his own reflection. Unable to leave it, he wasted away at the water's edge, and a flower grew where he died.
What the song hears
He chose the paralysis. He knows Echo is dying behind him, and he does not turn around.
