Completing the "Wedding Crashers" main quest in *Kingdom Come: Deliverance 2* can seem straightforward, but knowing where to find the newlyweds to offer your congratulations is crucial. Once it's evident that Otto von Bergow won't be attending Lord Semine's wedding, it's time to wrap up the quest and find an alternative way to meet him. To complete the quest, you must congratulate the newlyweds before leaving the celebration, but finding Agnes and Lord Semine can be challenging as they appear to be missing from the festivities.
Before you set out to find Agnes, ensure you've completed any other activities you want to engage in at the wedding. Once you start your conversation with her, it will lead to the quest's conclusion, transporting you to Trosky Castle. By this stage, you should have already experienced most of the wedding's additional content, which happens before the ceremony.
While mingling with the guests, you can ask if anyone knows the whereabouts of the newlyweds, but since no one can provide an answer, you can skip this step. Instead, head directly to Agnes's location. If you previously stole schnapps from the wine cellar, finding her becomes easier. Go to the main building and locate a group of people talking near the stairs. Across from them, you'll see a guard standing next to a door. This door leads to the wine cellar where you'll find Agnes, alone and in tears, indicating that the wedding did not go as planned.

When you speak with Agnes, your dialogue choices won't significantly impact the outcome beyond expressing your intent to congratulate the newlyweds. You'll discover that Olda, her new husband, has already left without her, a common occurrence where he keeps her in the dark about his travels. Depending on your choices in future quests, you might need to side with either Semine or Hashek.
Regardless of how your conversation unfolds, it will inevitably lead to a man stumbling into the cellar, sparking a brawl that engulfs the entire wedding. You can either wait out the time in the cellar or participate in the brawl, fighting whoever you encounter. The quest will conclude similarly in either scenario. Eventually, the fight transitions into a cutscene, resulting in both Henry and Hans being imprisoned at Trosky Castle.
That's how to congratulate the newlyweds in *Kingdom Come: Deliverance 2*. Your next step is to tackle the "For Whom the Bell Tolls" main quest, where completing tasks within a certain time limit can boost your reputation, adding pressure to your gameplay.
