You are cordially invited (S01E05)

As Karla and Egon prepare for their wedding, tension arises when Egon expresses his disapproval of Karla's son, Bimmer, attending the ceremony. Meanwhile, Mr. and Mrs. Clausen are embroiled in their own dispute, leading Mrs. Clausen to refuse to attend the wedding. In a moment of frustration, both Karla and Mrs. Clausen retreat to their bedrooms, isolating themselves from the festivities. Fortunately, assistance arrives, allowing Egon and Mr. Clausen to gain entry and hopefully resolve the brewing conflicts before the ceremony begins.
