In *Kingdom Come: Deliverance 2*, the "Wedding Crashers" main quest can seem straightforward, but finding the newlyweds to congratulate them might leave you scratching your head. As Otto von Bergow fails to show up at Lord Semine's wedding, your goal shifts to wrapping up the quest by congratulating the newlyweds before leaving the celebration. However, locating Agnes and Lord Semine proves to be elusive at first glance.
Before you set out to find Agnes, ensure you've completed any other tasks you want to do at the wedding. Once you engage in conversation with Agnes, the quest will move towards its conclusion, transporting you to Trosky Castle. By this stage, you should have already experienced most of the additional wedding content, which occurs before the ceremony itself.
While mingling with the guests, you might ask about the whereabouts of the newlyweds, but since no one has a clear answer, you can skip this step. Instead, head directly to Agnes' location. If you previously pilfered some schnapps from the wine cellar, you'll know exactly where to go.
When you approach Agnes, your dialogue options won't significantly alter the outcome beyond selecting the choice to congratulate the newlyweds. Agnes reveals that her new husband, Olda, has already departed without her—a habit of his, and one he doesn't fully explain. Your conversation with Agnes will set the stage for future quests, where you may need to choose sides between Semine and Hashek based on your decisions in the following main quests.
That's how you congratulate the newlyweds in *Kingdom Come: Deliverance 2*. Your next main quest, "For Whom the Bell Tolls," awaits, where the pressure is on to complete tasks within a specific time frame to boost your reputation.
