The developers of The Witcher 3 planned to include Triss's wedding in the game

In the Witcher 3's "Ashen Marriage" quest, set in Novigrad, Geralt assists Triss Merigold and her fiancé, Castello, with wedding preparations. His tasks include ridding the canals of monsters, procuring alcohol, and selecting a wedding gift for Triss. The gift's significance impacts Triss's response; a memory rose, a callback to Witcher 2, evokes a strong emotional reaction, while less sentimental gifts receive a cooler reception.

However, Dijkstra's revelation that Castello is connected to witch hunters throws a wrench into the proceedings. Castello's involvement stems from blackmail – the hunters threaten to expose his illegitimate daughter from a previous marriage.

Geralt can choose to reveal this truth to Triss, either with or without Castello's presence. Regardless, the wedding is called off. Triss's reaction varies depending on the circumstances, ranging from disappointment to gratitude for Castello's honesty, ultimately concluding that the marriage was premature.

This plot development offered a chance to enrich Geralt and Triss's dynamic and further explore the complexities of supporting characters.
