Ep 3. Love Machine

In the Haven season 2 episode 3, titled "Love Machine," the town is hit by an unusual affliction: anyone who is close to a particular vintage love seat becomes all-consumed with romantic feelings for the person sitting beside them. As Aubrey Plaza's character Luz watches in disbelief, people start making out in the streets, confessing their true feelings to long-time crushes, and otherwise behaving completely out of character.

The episode follows Audrey and Nathan as they try to uncover the origin of the love seat's power, which seems to be related to a curse placed on a family of furniture makers many years ago. They track down the last surviving member of the family, who seems to know more than he's letting on. Meanwhile, Duke finds himself becoming increasingly involved in the love frenzy, as a woman he's been seeing for a while falls under the love seat's spell and becomes her new soulmate. As he fights for her attention, Duke realizes that his feelings for her might be deeper than he thought.

As the episode progresses, Nathan and Audrey discover that the curse on the family was placed by a Haven resident with powerful supernatural abilities who wanted revenge for some wrongdoing in the past. They realize that the only way to stop the love seat's effects is to find and confront the person responsible. However, time is running out as the entire town has succumbed to the love seat's power, and emotions are becoming more and more heightened by the moment.

Ultimately, the team uncovers the source of the curse and finds a way to lift it, leading to a satisfying climax where the town returns to normal and people come to terms with their newfound feelings. The episode ends with Duke and Audrey discussing their own romantic entanglements, as Duke struggles to decide whether to pursue the woman he's been seeing or let her go in favor of Audrey, who he's been harboring feelings for all along. The episode leaves viewers on a cliffhanger, wondering who Duke will choose and what new challenges the people of Haven will face next.
