exploring-anne:

As usual, the series uses imagery that has some wonderful symbolism.  A butterfly is a tiny thing that starts out vulnerable and preyed upon (a caterpillar), seeks safety to be able to grow (a cocoon) and emerges as something lovely that can take flight (a butterfly).

Anne herself starts out vulnerable and preyed upon (an orphan), finds safety that allows her to grow (a family) and eventually emerges as something wonderful (an imaginative and more confident young woman).

This season is about about her growth.  So her finding kinship with a set of butterflies is a lovely visual parallel ❤
