Yasmin and Rashad Meet Dr. Tarek Tawfik at Ay's Tomb

Yasmin and Rashad tour Ay's tomb in the Valley of the Monkeys with Egyptologist Dr. Tarek Tawfik in an attempt to find out if the tomb really belonged to Ay, Tutankhamun's advisor, or if it belonged to Tutankhamun himself. Ay succeeded Tutankhamun after the Boy King suddenly died. Why was Tutankhamun buried in a small tomb unlike all the other pharaohs buried in the Valley of the Kings?
