Not sure at which step of the events you're at:
- You get an event when you talk with Trey at the sleeping chambers after using the teleport orb when the scene with f-Brad at the cavern of the enigmatic warlord is done.
- After the quest at Fürstenstein, you can do a race for a treasure, which also gives you a new CG scene afterwards.
- The CG scene is required to unlock a new dialog with one of Lady Purple's guys. (Also requires that you have married someone already.)
- This event will unlock a new wedding quest, and a new dialog with Tsiom when you finished all of her training with Brad and finished the fight between Brad and Grimace (regardless of the outcome).
- After the events with Tsiom, you can talk with Brad at the sleeping chambers to get a new dialog.
- The event will determine the future of Brad. One of the three choices will give you a dialog with Ash in Kagabangui, which leads to a new CG scene.
(If you took one of the other two choices in the dialog with Brad, the event and scene with Ash won't happen.)
