Frienship and Trust

Olive has gone to Annabelle (a woman inside a painting) because she knows she can trust here and maybe to even stay the night with her but Annabelle has lost a necklace that she loves and wants to go out of the painting and find it so Olive lets her out. My opinion is that I don't really trust Annabelle and letting her out because you never know what she could be hiding. What I think will happen next is that Annabelle might find out that Olive has her necklace but not get mad at her for wearing it but I'm not fully sure yet.
