House of Anubis S02E48 - House of Hex

Jerome's tournament goes badly. As Victor is getting ahead, Senkhara is getting angrier. She yells at Nina for visiting Gran instead of working through the tunnels. Nina gets upset and says that Senkhara doesn't exist and walks through her. Senkhara then tells Nina her punishment "will be to punish." The next day, Nina's innocent words to her friends are twisted by Senkhara into hexes. Nina gets a vision about herself turning into Senkhara and the Sibuna gang is running away from her.
