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 monster extermination, procuring alcohol, and selecting a wedding gift for Triss. The gift's significance impacts Triss's reaction; a memory rose, a callback to The Witcher 2, evokes a strong emotional response, while less meaningful gifts receive a cooler reception.
However, Dijkstra's revelation of Castello's ties to witch hunters throws a wrench into the proceedings. Castello, it transpires, is acting under duress due to the hunters' blackmail concerning a secret daughter from a previous marriage.
Geralt can choose to reveal this truth to Triss, either alone or with Castello. Regardless of his choice, the wedding is called off. Triss's reaction ranges from disappointment to gratitude for Castello's honesty, but ultimately, she deems the marriage premature.
This plot development offered a potential opportunity to enrich Geralt and Triss's dynamic and further explore the complexities of supporting characters.
