I really wondered that too. We know Valentina is her #1 follower, and Lydia is #2, even though her grandfather is not. Anna specifically spoke against Marius, whom Helen fawns too much over, but we escorted her to her private worship of Anna, who appeared smiling unbeknownst to Helen, so Anna seems pleased with her. She and Prosepina also see Cass and Aelinia as being loyal. They were concerned about Estrid's religion, but I don't think that's who Anna is talking about. I thought Nicabar had joined the first visit to temple in the game, so Kaylan should be fine.I'm curious which LI is the one Anna would never choose to be queen and what are our choices we get for the goddess.
