I'm developing the first draft of my WIP, refining structure, strengthening character motivations, filling plot holes. That sort of thing. The novel has jealousy as a basic theme. It currently includes a chapter where the best friend (and matron of honor) of my female main character talks sense into her after she's begun (falsely) to suspect her fiance of cheating on her. It's all projection--- she's done something earlier in the story that makes her fear she might be capable of cheating on him. So now I'm thinking I should have another chapter/scene earlier on to develop this, where the same best friend tells the FMC that what she did/thought/felt earlier on was completely normal, don't hassle it. But the way the new chapter is shaping up in my mind is very much like the chapter already written, and I'm afraid this best friend character is getting stereotyped into The Wise Counsellor, and the two scenes will essentially be the same. How have you solved this kind of thing?
