In *Kingdom Come: Deliverance 2*, completing the "Wedding Crashers" main quest can be a bit tricky, especially when you're tasked with congratulating the newlyweds. Once it's evident that Otto von Bergow won't be attending Lord Semine’s wedding, your focus shifts to wrapping up the quest and finding an alternative way to meet him. To successfully finish the quest, you must congratulate the newlyweds before leaving the celebration, but locating Agnes and Lord Semine can be challenging as they seem to be missing from the festivities.
Before you set out to find Agnes, make sure you've completed any additional tasks you want to undertake at the wedding. Engaging with Agnes will trigger the quest's conclusion, leading you to Trosky Castle. By the time you reach this point, most of the wedding's side content should already be completed, as it occurs before the ceremony itself.
While mingling with the guests, you might inquire about the newlyweds' whereabouts, but don't expect a helpful response. Instead, focus on finding Agnes. If you previously pilfered some schnapps from the wine cellar, locating her will be straightforward.
The Wedding Brawl
Regardless of your conversation with Agnes, a man will eventually stumble into the cellar, sparking a brawl that engulfs the entire wedding. You can either wait out the time in the cellar or join the fray and fight whoever you can. The outcome remains the same, leading to a cutscene where both Henry and Hans end up imprisoned at Trosky Castle.
That's how you congratulate the newlyweds in *Kingdom Come: Deliverance 2*. Your next challenge awaits in the main quest "For Whom the Bell Tolls," where completing tasks within a time limit can boost your reputation. Get ready for the pressure!
