Throughout the SeriesEdit
In The Swedes, Soren and Agneta come over from Interpol to help with the Diamond heist. Him and Agneta first appear cold and aloof to Rosa and Charles and will not eat their 'disgusting street food'. Soren and Agneta later go to the apartment of the suspect and investigate it without Rosa and Jake much to their annoyance. Soren and Agneta attend a Swedish millionaire's party and arrange a meeting with a potential buyer, much to Jake and Rosa's annoyance. Later when Jake and Rosa solve the case, Soren and Agneta are not annoyed, instead happy that they have the opportunity to learn. Jake tells them to go die in a Fjord and Soren and Agneta try and explain that they enjoyed working with them. Jake and Rosa still dislike them.
Agneta is shown to be very close to Lars. He is shown to be hardworking as well as slightly dismissive and condescending at times. She is shown to be helpful to Soren such as scheduling his dentists appointment to avoid it clashing.
Soren and Agneta are extremely close. They frequently hold hands and perform tasks for each other such as rescheduling dentists appointments and donating sperm without being asked. Soren and Agneta also frequently sauna together so that they have no secrets from one another, even their bodies. Agneta also would want Soren to be there if she broke up with her husband, Lars so that Lars would have shoulder to cry on.
Soren and Agneta are very fond of Jake and Rosa, despite Jake and Rosa's evident dislike of the pair. Soren and Agneta often accidentally appear condescending and dismissive towards the pair which annoys them immensely. Despite this, Jake does trust them enough to go to them for advice, even though he eventually dismisses what they have to say. Agneta fondly calls them 'Yake' and 'Rosie'.
Lars is Agneta's unseen husband back in Sweden. The two have a child together although the biological father is actually Soren Knausgaard as he had his sperm ready in a Tupperware when Agneta and Lars were having trouble conceiving.
