This guide details how to romance Katherine in Kingdom Come: Deliverance 2. This involves completing several key quests and making specific dialogue choices.
Key Steps to Romancing Katherine:
1. The King's Gambit: Early in the game, during "The King's Gambit," you'll spend a night in Suchdol. While in Sigismund's camp, Katherine will bathe you. Select the dialogue options: "It's different with you," and "What about a kiss for luck?" to initiate the romance.

2. Completing Katherine's Side Quests (Kuttenberg): After "The King's Gambit," complete two side quests in Kuttenberg:
- The Fifth Commandment: Help Katherine track a serial killer. Crucially, let Katherine kill the killer instead of turning him in. This is vital for progressing the romance.

- The Stalker: Help Katherine deal with a stalker. You can resolve this through speech, bribery (200 groschen), or combat.
3. The Italian Job: Progress through the main questline until you reach "The Italian Job." Before speaking with Jan Zizka, find Katherine in the minting room courtyard. Compliment her.
4. Hunger and Despair: In the main quest "Hunger and Despair," after the battle and speaking with Zizka, find Katherine in the infirmary. Choose the dialogue option: "I'll bring help, and everything will be alright again." Finally, meet her at the ramparts to conclude the romance.
Following these steps ensures a successful romance with Katherine in Kingdom Come: Deliverance 2. Consult other resources for additional gameplay tips, such as whether to kill Jakesh or locating the Cumans' Camp.
