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, in their hasty 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 is noteworthy; a memory rose, a callback to The Witcher 2, elicits a strong emotional response from Triss, unlike simpler alternatives.

However, Dijkstra's revelation that Castello is connected to witch hunters throws a wrench into the proceedings. Castello's involvement is revealed to be coerced; witch hunters blackmail him, threatening to expose a secret concerning his daughter from a previous marriage.

Geralt has the option of disclosing this information to Triss, either privately or with Castello present. Regardless of his choice, the wedding is called off. Triss either expresses disappointment in her fiancé or appreciates his honesty, ultimately deeming the marriage premature.

This plot development had the potential to enrich Geralt and Triss's dynamic and further develop supporting characters.
