thank you for your answers.1. only one paperweight is ever available for sale. The rustic stones are only available if you have under 20 mana
2. Kate's appearances very much depend on your interactions with her, for instance insulting her in the first meeting. I have not checked your save yet, what happened last with her?
3. How long has Mrs Granger been in the hospital, she recovers from the ER based on other events
4. sonds like a mnor bug in the notes, if you did the Ritual not a problem
5. Dr Kay has limited meetings, did you charm her on any of your meetings? The hospital is an alternative to the school to charm her. The hotel is mostly post charm, but does very much depend on time of day
6. talk to her, it will advance story lines including Kate's and Leanne's
7. as noted talk to Legion
8. the bath scene depends on if you accepted to go upstairs when Lauren mentions Sarah is taking a bath. if you leave all further events a locked out
9. do you have the vase? If not get it, charm Gina is the usual way though invisibility will allow you to get it too
However... quote from walkthrough
"You can find a paperweight for 3$ in the general store. You can free the Stone inside at the Wild Ranges. You can only have one paperweight at a time." -> that implies you are able to buy them constantly, just as you can ask for more letters of credit from Gates if you have under 30 bucks and don't have a letter in inventory. NO rustic stones for sale either.
Kate: studied together, answer correctly to the bet, saw her breasts and bottom.
Kay: had a checkup in hospital, she invited me to meet her in the evenings to tell me more. Did not tried to charm her (no shielded charm)
Vase/Gina: don't have the vase, Gina is charmed (as well as museum curator)
