When you are referencing one of the GFD stories then there are some guidelines to follow. You should always use this format:
"The reason every vampire's extra is different, is because it reflects the kind of people we were when we were alive. Therefore, by looking into your psyche, we'll determine what new surprises we can expect to see as your powers manifest themselves." - Tim, Gone From Daylight: The Beauty and the Darkness.
Which can be broken down into: The character who said the quote (if it is a quotation, it is unnecessary to quote Justin as the narrator, only in speech or thoughts), The story name, in full (no abbreviations) and the name of the chapter, with a link directly to the page that the quotation etc. is on. These link should always be in italics.
