In the Witcher 3 quest, "Ashen Marriage," Geralt assists Triss Merigold and her fiancé, Castello, in their preparations for a swift wedding in Novigrad. His tasks range from monster extermination in the city's canals to procuring celebratory beverages and selecting a wedding gift for Triss. The gift's significance impacts Triss's response, with a memory rose (a nod to The Witcher 2) eliciting a strong emotional reaction.
However, unforeseen complications arise when Dijkstra reveals Castello's connection to witch hunters. This revelation unveils a coercive element to Castello's actions—he's being blackmailed to conceal his illegitimate daughter from a previous marriage.
Geralt faces the choice of revealing this truth to Triss, either privately or with Castello present. Regardless of his approach, the wedding is inevitably called off. Triss's reaction varies depending on the circumstances, ranging from disappointment to gratitude for Castello's honesty, but ultimately concludes that their rush to marriage was ill-advised.
This plot development presents a missed opportunity. A more thorough exploration of this storyline could have enriched the relationship between Geralt and Triss, while also providing more substantial character development for supporting characters.
