House of Anubis S01E23 - House of Numbers

It is Nina's unlucky day when Victor padlocks the attic door to stop her going up there again after seeing her go in. Victor even catches Nina doing something, which ruins everything. She does not even know the worst part yet - Jerome has contacted Rufus by getting Rufus's number off Patricia's phone and is now spying on Sibuna for Rufus after being bribed. Sibuna plan to go down into the cellar to collect some of the elixir and to try to crack the latest clue. Alfie draws the short straw, but this time he will have a walkie talkie to maintain radio contact. However, Jerome secretly sabotages the whole mission by taking Alfie's walkie talkie. He almost gets caught by Victor twice and manages to escape the second time by hiding in the sarcophagus. Jerome shuts and locks the sarcophagus with Alfie still inside.
