When we first meet Eve’s husband, Niko, in season one, he serves as a foil to her very unconventional work life. He reminds us that, despite being obsessed with female assassins, Eve is still a seemingly normal person; that presumably when they met, fell in love and got married, Eve was in many ways the same as any Jane Doe. He tethers her to real life in a way that none of her work colleagues, who have grown so accustomed to the gruesome and harsh realities of their jobs (except perhaps for sweet, innocent Kenny), can do. In short, he makes her and her life appear relatable.
Things start to fall apart as Eve gets closer and closer to Villanelle, but at least for season one it looks like nothing a little apologizing and quality time won’t fix. Once we enter season two, however, it becomes ever more clear that Niko does not exactly like this new side of Eve.
Although Niko tells Eve that he understands she needs to solve the Villanelle case (so long as she is honest with him about it all, which is a fair request from a spouse), that support doesn’t last very long—even after she shows up at his faculty cocktail event in a “definitely too sexy for teacher drinks” dress he picked out for her, we might add. (Sure, she pulls the fire alarm and puts a damper on the event, but it was because she was worried that Villanelle might be in the building hunting her or her loved one down.) As Eve’s case grows more interesting, Niko grows more irritated. And honestly, so did I. Except that the person I became irritated with was Niko.
