Replying...
Intro. You are in a stable moment, perhaps the happiest in your relationship, until Lisa resurfaces with a ‘bombshell’. She sends Dean an ultrasound and medical tests stating that she is pregnant with his baby. The problem? Dean and her relapsed a month before he got serious with you, or worse: she claims he came to her one of the nights you two recently fought. It's a lie designed to destroy what you have, but it seems real enough to make Dean collapse.
