Haha...no, the "spurned lovers" was a theme...I wrote the lines to sound like something "spurned lovers" would say to the one who spurned them...I actually thought up the clues separately and then realized that it would be a good theme, that would allow me to put in certain hidden clues (like "you'll never come back" a revealing clue that hides nicely in a dialogue between a spurned lover and a spurner )
The "big picture" I refer to is the entire puzzle, which is what you have to look at to figure out the identity of the spurner, which is probably the best first step in solving the riddle...also I might have used "big picture" to refer to looking at the meanings of lines instead of focusing on individual keywords, which may obfuscate the matter...
