Locating the Newlyweds in Kingdom Come: Deliverance 2's "Wedding Crashers" Quest
Some seemingly straightforward quest objectives in Kingdom Come: Deliverance 2 present unexpected challenges. The "Wedding Crashers" main quest concludes with congratulating the newlyweds, but finding them proves tricky.
After realizing Otto von Bergow won't attend Lord Semine's wedding, the quest shifts focus. To complete it, you must congratulate the newlyweds before leaving the festivities. However, neither Agnes nor Lord Semine are readily apparent.
Complete any other wedding activities before speaking with Agnes. This conversation concludes the quest, leading to imprisonment in Trosky Castle. Most optional wedding tasks occur before the ceremony.
While you can inquire about the newlyweds' whereabouts from other guests, this yields no results. Instead, proceed directly to Agnes' location. If you previously pilfered schnapps from the wine cellar, finding her is simpler.

Enter the main building. Near the stairs, a group converses; opposite them, a guard stands beside a door leading to the wine cellar. Agnes is found here, alone and distraught, indicating the wedding's unexpected turn.

When speaking with Agnes, select the option to congratulate the newlyweds. You discover Olda, her husband, has departed without explanation, a recurring pattern. Your choices here influence later quests, potentially requiring you to side with Semine or Hashek.
Regardless of your conversation, a brawl erupts, initiated by a man entering the cellar. You can either wait out the fight or participate; the quest outcome remains the same. The brawl culminates in a cutscene, resulting in Henry and Hans' imprisonment at Trosky Castle.
This concludes the "Wedding Crashers" quest. Next, you'll tackle "For Whom the Bell Tolls," where timely task completion impacts your reputation.
