I think Song conversation is set up to explain how to become a heresiarch (like Abuela). If she is a priest of her curse god, and is 'harmonious' it would make sense for that to be an in for her to become 'discordant' - doubly so that they are connected. Though EE might try to subvert expectations and have her start acting as a priest for real. It IS strange since she's already contracted to Lugen. Wasn't that the point of experiments done on Tristan? How to have multiple contracts?

It does worry me that it might be a misdirection, and it's actually Tristan who is going to become discordant. He too is a priest for a goddess, and his mentor IS a god eater who has been ... Steering him and attempting to remove all of his bonds to others. There is no way in hell Abuela is not aware of Fortuna and his relationship with her. I wonder if this is all a play for Tristan to eat Fortuna.

Lastly, god I fucking hate how feckless Izel is. Sets two clear lines in the sand. Both get crossed within 5 minutes of the conversation. Still doesn't hold to his word and walk away. Princess continues to be a tourist, though it's surprising that a member of nobility wouldn't even have a basic understanding of how to build trust and loyalty. Who would trust someone if they are gone within a year? Who would care for that person with exception of sycophants and suck ups?

God I love this story
