Reached 4/12! Mum is gettint better and better at exploring 3D environments, and is able to intuit where to go based on their environments now - her instinct was to go to the branch off the main hall for the faculty office (although got lost anyway due to lack of signposting), beelined to the stairs when told to go to the roof. Also made the classic mistake of going backwards on the roof door room because she was holding forwards, teaching her a little lesson about how movement input always corresponds to camera placement! Besides that, is happy that she finally has a better idea what's happening after Morgana's expository dialogue, and learned that auto-advancing cutscenes is actually more convenient. (Also noted that a lot of the dialogue doesn't contain essential information but just nudges the flow of conversation along bit by bit)
