Question on influence on Visas (Star Wars: Knights of the Old Republic 2 - The Sith Lords)

Decided to replay the dialogue. I remembered that when my father passed, he somehow learned the Vision of Power through 1 dialogue with Visas. I thought he just learns about the world (well, he loves lore in games very much), but apparently not. I lived through all the lines of dialogue with her, but I never received a vision. What would ... (quietly, such a nizya) you need to press in order to get through the dialogue?
