I wonder why Belaf's intuition was not to reveal anything about Faputa's origin (also I wonder how much Belaf exists within Nanachi). They basically reveal it anyways after Nanachi gets crippled and they talk about the alcohol, but I don't feel like Srajo's going to do anything about it. The only thing I think could "trigger" Srajo based on Nishagora's arm writing is if she tries to talk to Srajo's white whistle (which is a big no-no since that could reveal the origin of her white whistle, and maybe even why she carries so many whistles).
