In case no one noticed. This dancing girl represented Mary Dilaurentis. Hence, why Spencer mentioned she looked like a young Alison.

The scene also alluded to child birth based on several of her dance moves.

This portrait is older which alludes that this girl is grown now–more hints toward Mary. Additionally, this is the first instance the girls found out about Carissimi. Maybe this is also why Mary said, “We can finally take back, what’s supposed to be mine”

Turns out this was not a lost story after all.
