So did they ever explain how Roxana saving Cassis would help her survive? Is it so the Pedelians don’t come after her for saving their son or something? Or a different reason?

If I’m not wrong, Cassis eventually brings down the Agriche house. Roxanna basically has nothing left to live for, and even if she tried to survive, the poison butterflies would kill her eventually. Cassis purified her and told her to “give her remaining time to him”. So this helped her survive, and it meant she wasn’t a target of the Pedelians because they love her a lot since she’s the one who saved their son
