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

In the Witcher 3 quest, "Ashen Marriage," Geralt assists Triss Merigold and her fiancé, Castello, with wedding preparations in Novigrad. 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, unlike less sentimental choices.

However, a surprising revelation from Dijkstra exposes Castello's connection to witch hunters, casting doubt on his intentions. It transpires that Castello is being coerced—blackmailed into the marriage by threats against his daughter from a previous relationship.

Geralt can choose to reveal this truth to Triss, either privately or with Castello present. Regardless, the wedding is called off. Triss either expresses disappointment in her fiancé or appreciates his honesty, ultimately deeming the marriage premature.

This unexpected turn could have deepened Geralt and Triss's dynamic and provided more substantial character development for supporting characters.
