Nearly Headless Nick fanfiction idea?

It sounds really good! I don't know if this is what you intended to do or not, but maybe the woman could be the reason he's executed? Maybe the wizarding community does decide to execute her (after a miscarriage maybe?), but Nick falls in love with her and wants to protect her, so gets executed for treason too? You don't have to use my ideas, but I think it'd be really interesting what ever you decide to do. Good luck!
