In the Witcher 3's "Ashen Marriage" quest, set in Novigrad, Geralt assists Triss Merigold and her fiancé, Castello, in their wedding preparations. His tasks range from monster extermination in the city canals to procuring alcohol and selecting a wedding gift for Triss. The gift's significance impacts Triss's response; a memory rose, a nod to Witcher 2, evokes a strong emotional reaction, unlike simpler presents.

However, Dijkstra's revelation of Castello's connection to witch hunters throws a wrench into the proceedings. Castello, it transpires, is under duress, blackmailed by the hunters who threaten to expose his illegitimate daughter.

Geralt faces the choice of revealing this truth to Triss, either alone or with Castello. Regardless of his approach, the wedding is called off. Triss's reaction varies—disappointment in her fiancé or gratitude for his honesty—but the hasty nature of the planned marriage is ultimately deemed inappropriate.

This plot development offered a potential opportunity to enrich Geralt and Triss's dynamic and further develop supporting characters.
