In the context of 'Family Guy', Diane could potentially be a love interest for one of the secondary characters. For instance, if it's a story about Quagmire, Diane could be someone he meets and has a short - lived relationship with. Or she could be a relative of a character that shows up unexpectedly and stirs things up in Quahog. Without more details, it's difficult to determine exactly who Diane is in this story.
Since I don't know the exact 'Family Guy Diane Story', Diane could be anyone. She might be a new character introduced for a single - episode plot. Maybe she's an old acquaintance of one of the main characters like Lois or Peter.
Diane in the 'Family Guy Diane Story' could be a character created to bring a new dynamic to the show. She could be an artist who moves into the neighborhood and tries to convince the Griffins to participate in some sort of community art project. Or perhaps she's a scientist doing some wacky experiments nearby and the Griffins get caught up in her scientific mishaps. But again, this is all based on speculation as we don't have the full details of the 'Diane story'.
