Completing the "Wedding Crashers" main quest in *Kingdom Come: Deliverance 2* might seem straightforward, but knowing where to congratulate the newlyweds can be tricky. As the quest progresses and it's evident that Otto von Bergow won't be attending Lord Semine's wedding, your focus shifts to wrapping up the quest by finding a new way to encounter him. To successfully complete "Wedding Crashers," you must congratulate the newlyweds before departing from the celebration. However, locating Agnes and Lord Semine can be a challenge as they seem to be missing from the festivities.

Before seeking out Agnes, ensure you've completed any additional activities at the wedding, as speaking with her will initiate the quest's conclusion, transporting you to Trosky Castle. Most of the extra content at the wedding occurs before the ceremony, so you should be set by the time you need to find Agnes.

Engaging with other party-goers might lead you to inquire about the newlyweds' whereabouts, but none of them will have the answer. Instead, make your way to Agnes' location. If you previously pilfered some schnapps from the wine cellar, navigating to her becomes easier.

The Wedding Brawl

Regardless of how the conversation unfolds, it will eventually lead to a man stumbling into the cellar and igniting a brawl that engulfs the entire wedding. You can either wait out the chaos in the cellar or join the fray indiscriminately. The outcome remains the same, culminating in a cutscene where both Henry and Hans find themselves imprisoned at Trosky Castle.

That's how you congratulate the newlyweds in *Kingdom Come: Deliverance 2*. Your next step is to tackle the main quest "For Whom the Bell Tolls," where your reputation is on the line, contingent on completing tasks within a strict time frame. The pressure is indeed on.
