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 response; a memory rose, a callback to Witcher 2, evokes a strong emotional reaction, unlike more mundane presents.

However, a surprising revelation from Dijkstra exposes Castello's connection to witch hunters, casting doubt on his intentions. It's revealed Castello is coerced, blackmailed into the engagement to protect his daughter's secret from a previous marriage.

Geralt can disclose this truth to Triss, either privately or with Castello present. Regardless, the wedding is called off; Triss is either disillusioned or appreciative of Castello's honesty, but ultimately deems the marriage premature.

This unexpected turn could have enriched Geralt and Triss's dynamic and further developed supporting characters.
