Trust Broken??

Olive just let Annabelle out of her painting and now they are wondering around the house and Annabelle says that her necklace is in the painting with the big lake in it so they go in the painting. I kinda knew that Annabelle was weird and couldn't really trust her but Olive made the choice too. What I think will happen next is Horatio and Olive might find Annabelle somewhere but I'm not sure what from then.
