We're giving it an entire week before he moves again? Alright. I'm a little tired right now (as it's midnight) so forgive me if I'm not brimming with genius at the moment. We need an identity of a student the lackey is possessing, but it can't be someone who stands out too much and keeps to themselves like Kurama. I think because Botan is stronger in spiritual energy than the average human it may take a great deal longer for the suicide thoughts to fully emerge, but Kurama and Shiori do start to see her attitude change as Friday approaches. Maybe she's more aggressive or uncharacteristically quieter? Kurama would see the signs though, so there has to be a reason he wouldn't break her out of it earlier than when she's about to kill herself.
