One evening, Lars happily announces to Gus and Karin that he has a visitor whom he met online, a wheelchair-mobile missionary of Brazilian and Danish descent named Bianca. The pair are startled to discover that Bianca is actually a lifelike doll, ordered from an adult website, whom Lars treats as a live human being. Concerned about his mental health, Gus and Karin convince Lars to take Bianca to see the family doctor, Dagmar Berman, who is also a psychologist. Dagmar diagnoses Bianca with low blood pressure and urges Lars to return under the guise of "weekly treatments" for Bianca, while actually analyzing Lars to get to the root of his behavior. Dagmar explains to Gus and Karin that Lars' delusion is a manifestation of an underlying problem that needs to be addressed, and that they need to assist with Lars' therapy by continuing to treat Bianca as if she were real. During this time, Margo has begun to date another co-worker, which silently bothers Lars.
