Finding the newlyweds in *Kingdom Come: Deliverance 2*'s "Wedding Crashers" quest might seem straightforward, but pinpointing their location can be tricky. After discovering Otto von Bergow's absence from Lord Semine's wedding, the quest shifts focus to congratulating the happy couple. However, neither Agnes nor Lord Semine are readily apparent.
Before searching for Agnes, complete any other wedding activities. Speaking to Agnes triggers the quest's conclusion and transports you to Trosky Castle. Most optional wedding content precedes the ceremony, so you should be nearly finished by this point.
While you can ask other wedding guests about the newlyweds, they won't offer helpful information. Instead, proceed directly to Agnes. If you previously pilfered schnapps from the wine cellar, locating her is easier.

Enter the main building. A group converses near the stairs; opposite them, a guard stands beside a door leading to the wine cellar. Agnes is found here, alone and distraught, revealing the wedding's unexpected turn.
When you speak with Agnes, your dialogue choices are largely inconsequential beyond expressing your congratulations. You discover Olda, her husband, has departed without explanation, a pattern in their relationship. This information influences later quests, potentially requiring you to side with Semine or Hashek.

Regardless of your conversation, a brawl erupts, drawing you into the chaos. You can choose to wait it out or participate; the quest outcome remains the same. The fight culminates in a cutscene, leading to Henry and Hans' imprisonment in Trosky Castle.
This concludes the "Wedding Crashers" quest. Your next main quest, "For Whom the Bell Tolls," challenges you to complete tasks within a time limit, impacting your reputation.
