How does Annemarie take care of Ellen?

Annemarie watches over Ellen. She comforts and supports her. She is also able to think quickly for Ellen. Annemarie realizes that Ellen is still wearing her gold Star of David necklace. She panics and instructs Ellen to take it off, but Ellen has never removed it before and cannot undo the clasp. Desperate, Annemarie rips the necklace off Ellen's neck and crumples it in her hand moments before the officers barge into the room.
