I love episode ten for finally giving Mary the chance to breathe, when until this point the narrative has solely focussed on their stories of Jim and men. Claudia O'Doherty brings Mary to life as someone just as complex and unhinged as her devastatingly selfish "deceased" husband.
Kristen Johnston does as much as humanly possible in a single episode to deliver the spectacular Widow Evelyn Higgins, another larger-than-life character who seems to inhabit the entire series despite only appearing at the end.
In a show that is essentially about toxic masculinity, delivering these two rich female characters right at the end helps round out the perfect, devastating conclusion to season one.
