I don't think I answered these.
12) Whether or not you say your are a new student when you speak with Kiki.
I think so.
13) Whether or not you claim to have seen Titania chatting with a grunt in the woods.
Tried both times to see what happened. She knows you saw, and calls you out if you lie. It's a trap question, so I just said yes.
14) Whether or not you admit to reading the diary.
Another trap question. I said yes. Maybe I get 0.001 brownie point for being honest when she asks these questions.
15) Whether or not you tell Amaria what was in the diary.
Decided not to tell. I knew she'd read it anyway, but I felt like I owed her at least that. Honestly, if it were me in the game, I'd never have read the diary in the first place. I'd just wait for Titania to come back with Surf. But of course, you need to read it for that to happen.
