"The main source of conflict is going to be between Lindsay and Voight," showrunner Matt Olmstead told TV Guide. "She obviously tried to dissuade him from taking the law into his own hands, and he was dead set on going forward. So, what we have is her trying to come to terms with what she is pretty sure he did." (Matt Dinerstein/NBC)
