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 wedding preparations. 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, elicits a strong emotional reaction, unlike more commonplace presents.

However, Dijkstra's revelation of Castello's connection to witch hunters throws a wrench into the proceedings. Castello is revealed to be under duress, blackmailed by the hunters who threaten to expose his illegitimate daughter from a previous marriage.

Geralt can choose to disclose this information 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, concluding the marriage was premature.

This unexpected turn could have enriched Geralt and Triss's dynamic and further developed supporting characters.
