Summary
Analysis
Amelia leaves a note under Juliet's door inviting her to come for raspberry pie in the afternoon. Juliet sends Kit with her reply, explaining that she has a guest and won't be there but Kit would love some pie.
These small notes allow the islanders to continue to connect with each other while also providing each other space.
