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 monster extermination in the canals, procuring alcohol, and selecting a wedding gift for Triss. The gift's significance impacts Triss's response; a memory rose, a nod to The Witcher 2, evokes a strong emotional reaction, unlike simpler presents.

However, Dijkstra's revelation of Castello's ties to witch hunters throws a wrench in the proceedings. Castello's involvement stems from blackmail – the hunters threaten to expose his daughter from a previous marriage.

Geralt can disclose 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, concluding the marriage was premature.

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