They quickly get a picture of their "ghost" (which happens to be Amber) during their cellar stake out. With photographic evidence and Mara's theory that their ghost is the "Unknown Ruler", their story could destroy the Sibuna's secret mission! Nina realizes that the dollhouse is missing and Jerome gives the dollhouse to Jasper who calls the Collector about it. The Collector takes the dollhouse and doesn't bring Trudy back.
