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, 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 simpler alternatives.

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

Geralt can choose to disclose this information to Triss, either alone or with Castello. Regardless, the wedding is called off. Triss either expresses disappointment in Castello or appreciates his honesty, deeming the marriage premature.

This plot development offers a chance to enrich Geralt and Triss's dynamic and further develop supporting characters.
