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 choice impacts Triss's response; a memory rose, a callback to Witcher 2, evokes a strong emotional reaction, while less sentimental gifts receive a cooler reception.
However, a significant plot twist emerges when Dijkstra reveals Castello's connection to witch hunters, casting doubt on his intentions. 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 can choose to reveal this truth to Triss, either alone or with Castello. Regardless, the wedding is called off. Triss's reaction varies depending on the revelation's delivery, ranging from disappointment to gratitude for Castello's honesty, but ultimately deems the marriage premature.
This unexpected turn could have significantly enriched Geralt and Triss's dynamic and further developed supporting characters.
