Mara is furious as a heartbroken Joy admits her feelings for Jerome. Eddie calls on Patricia's sister for help with the missing artefact clue and KT is torn as she realises she doesn't know who to trust.

Frobisher finally wakes up and as the Sibunas predicted, he's evil. Joy tells Willow and Mara about Jerome's two timing ways. Victor and Denby force Mr Sweet to take drastic action against the Sibunas.

When Fabian's trusting nature lands him in the hands of Frobisher, Ammut's collection is almost complete. Eddie realises the Sibuna traitor is not KT and Jerome shocks Joy with a surprise ending to their play.

KT's hopes of proving her innocence disappear when Harriet is sectioned. The Sibunas search for the artefacts with the help of a family rhyme when the phonograph is mysteriously restored.

The Sibunas uncover the details of the secret ceremony in a very special place. They rush to rescue Harriet Denby, but discover she's gone. Jerome's love life is in a tangle.

The adults are on the Sibunas' tail, looking for their second sinner. Patricia plans to tell Eddie how she really feels about him, little knowing that Victor and Denby have trapped him in the crypt.
