This might just be one of the greatest, most generational collabs I have ever borne witness to. I really hope she does more with the Chinchilla (Aoi love too, but specifically Natsumi since they haven't done anything together before and it went far better than we could ever have dreamed of).
Edit: I think Pippa could get by with some vocab flashcards. Grammatical rules are important, but she's doing fine without knowing a ton of them, could use some conditional stuff like ば though.
