The developers of The Witcher 3 planned to include Triss's wedding in the game

In the Witcher 3's "Ashen Marriage" quest, set in Novigrad, Geralt assists Triss Merigold and her fiancé, Castello, with their impending nuptials. 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, while less sentimental presents receive a cooler reception.

However, Dijkstra's revelation that Castello is secretly 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 can choose to reveal this truth to Triss, either privately or with Castello present. Regardless, the wedding is called off. Triss is either disheartened by her fiancé's deception or grateful for his honesty, ultimately concluding that their rushed engagement was ill-advised.

This unexpected turn of events presents a missed opportunity. The storyline could have been enriched by further exploring the ramifications for Geralt and Triss's relationship, and by providing more substantial development for the supporting characters involved.
