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, reminiscent of The 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 is revealed to be acting under duress, blackmailed by the hunters who threaten to expose a secret about his daughter from a previous marriage.

Geralt has the option of revealing this truth to Triss, either alone or with Castello. Regardless of his choice, the wedding is called off. Triss is either disappointed in her fiancé or appreciative of his honesty, concluding that their rushed engagement was a mistake.

This unexpected turn of events could have been used to further explore Geralt and Triss's relationship and provide more nuanced character development for supporting characters.
