In the Witcher 3 quest, "Ashen Marriage," Geralt assists Triss Merigold and her fiancé, Castello, in their preparations for a hasty wedding in Novigrad. 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, unlike more mundane presents.

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 has the option of disclosing this information to Triss, either privately or with Castello present. Regardless of his approach, the wedding is called off. Triss's reaction varies; she's either disappointed in her fiancé or appreciative of his honesty, but ultimately concludes the marriage was premature.

This plot development offered a chance to deepen Geralt and Triss's dynamic and further develop supporting characters, adding layers to the narrative.
