House of Double-Cross

The Sibunas realize they must play the ancient Egyptian game of Senet - and the stakes are high. Joy is still getting a hard time because of Mara, so when Mr Sweet tells her to enter Mara in the blog competition, Joy makes other plans. Trudy is having strange dreams - could her memory be returning? Victor and Vera secretly practice Senet in his office, while the Sibunas meet Jasper who tells them Rufus knows he's been tricked, and he does it soon after the Sibunas find the rules on a mismatched tile on the library floor. Jerome finally makes his move on Mara, only to discover she's still not over Mick. Down in the tunnels, disaster strikes when Nina moves to the wrong square and the floor gives way beneath her.
