But Rufus is circling closer to the Mask in the tunnels, as is Victor! It's a race against time for find the true Mask. Meanwhile, at Jerome's dad's hearing, Mara and Poppy wish Jerome hadn't disappeared. Unlike Mick, who still believes that he's the careless joker he knew before he left. Over at the house, Eddie begins to act strangely. He begins to hear voices whispering "Chosen One" and "Osirian". When he picks up Jerome's gem that he had given him, it glows hot in is hand. He then hears more voices that say "Chosen One - find Nina". He runs off to the Frobisher library, now desperate to find her. Senkhara is close to getting what she has longed for as the Sibuna's find the true Mask in the exibition. Eddie runs in to the library with the Gem and Nina realizes that he is the Osirian. She takes the Gem from him and puts it in the Mask. She puts it on as it cries Tears of Gold. Senkhara then possesses Nina's body and she starts to walk towards the portal to the afterlife. She tries to throw a lighting bolt at Fabian, but Joy pushes him out of the way, leaving her to get hit and pass out on the ground. Eddie takes action and gets Senkhara's diadem that was displayed in the exibition. He points it at Nina and knows exactly what to say, banishing Senkhara from Nina's body. Rufus will not give up as he takes the Mask from Nina. As he puts it on and Senkhara goes into him and a fiery portal opens up to the Egyptian underworld. He falls in along with Senkhara. The Mask is left on the ground. Rufus an Senkhara are gone, but Joy is still unconsious on the ground, her face gray. Fabian and the others are scared as they cannot find a pulse. Nina spots the Mask on the ground with one last Tear of Gold on it. She gives it to Victor who puts it up to Joy's mouth. The color returns to her face and as she coughs. Everyone around her is sighing in relief. The Sibuna's then realize that their marks are gone. Alfie takes the Gem out of the Mask and is ready to give it back to Jerome, who has unknowingly already gone back to the house.

After almost everyone has left, Victor explains to Nina that only the pure of heart can enter the afterlife and become a God. Nina gives him the ring that his father's ghost had given her. Back at the house, the end of exibition party is taking place. Mara seems upset with Jerome for missing his dad's hearing, when Alfie comes in to give him the Gem.
