I was so focused on dealing with the Church that I forgot about any other threat. By the way, I haven't heard from Adelphium yet.
The Queen Grandmother hadn't made her appearances in a long while, making me hope she's giving up. However, the man visiting the Prince has been spotted near my lodgings a couple of times.
She's pretending not to care. What if everything about her is a pretence, even her hate towards Ignis? I wouldn't say she loves him, that's impossible, but she might not hate him so badly.
If she sent him to a safe place, she does care about him. Or about the honour of the Royal Family, whatever. Even her visits to Lars... Well, not her visits, but sending her man to check on him might be because of the same reason.
Maybe, just maybe, she's not trying to kill us. Or, at least, not Ignis and Lars. I might be another story.
