But O-Chul doesn't really know about the Godsmoot either. Assuming V sent a sending to him (which I'd question, as it's not like him knowing is going to help), it's limited to 25 words. He and Lien didn't react with a huge amount of relief when V said crisis had been delayed, which you'd expect from two people who'd found out Deus was Exing your Machinas.
The Godsmoot isn't going to be important in this book (unless it is), as it was mainly a driving force in the last book and now mostly out of the protagonists hands. I doubt Serini knows or cares what the Gods are doing, as she's got zero ability to affect that outcome.
