AVClub: Whereas the discomfort in “Scrapbook/Skidresa” reads as one-sided, its follow-up, “Parental Guidance/Svartsjuk” is the first episode of season two to really lean into Welcome To Sweden’s knack for discomfort comedy. Naturally, the second coming of Nancy and Wayne brings a lot of dysfunction to the table. There’s a darkness to Welcome To Sweden that’s not always at the surface. “Parental Guidance/Svartsjuk” deep-dives into that darkness with its rather grim outlook on relationships, building on what Viveka and Birgir dig up on the ski trip last episode.
