At the moment, I'm writing a story that is somewhat unrealistic and implausible. Okay, it's certainly unrealistic and reeks "implausible plot line" from about Chapter 14. During one intense scene in my novel, my characters are persuaded to agree to something I don't think anyone would rationally do, much less these guys simply because the character who wants them to do the favour manages to relate to them. She says how unfair the system is, rants a bit and ask her to do something which is almost certainly impossible. Firstly, are there any other things I could bring up to realistically persuade my characters to do something really, really stupid? And secondly, how are you able to limit unrealistic aspects of your stories and do you try hard to do so? Thank you!
