Our reading
An editorial interpretation.
Saying someone has 'gone bye-bye' gives an unsettling absence or loss of usefulness a childish, casual sound. The question that follows immediately turns toward whatever options remain. The contrast makes the speaker sound flippant even while asking for something practical to work with.
