Hopefully from what we've heard of the spoilers so far and from what Anthony Zuiker said in TV Guide (which I got in the mail today), about them having an "interesting moment" in the first 4 shows, that will be the end of it. Since I've never seen an ounce of chemistry between them, maybe it will fizzle out by episode 4 and they will be over it.
There was another quote from Carmine in the TV Guide that says: "It's the whole country girl vs. city guy kind of foreplay thing with us," Giovinazzo says of Danny and Lindsay.
Also, the thing about Stella leaving. I think the spoiler may have been about Mac having a girlfriend and the fanfic author just took it a step further. One little spoiler can contribute to a lot of fiction.
