Ayesha asks for Heston’s advice when diagnosing a patient with unusual symptoms. When Heston checks the young boy over, he says his symptoms could be the consequences of taking the drug Viper. The boy’s mother is livid at Heston’s suggestion and Zara disagrees with Heston’s diagnosis. Is Heston obsessed with the drug – or could he be right?
Later, Heston sees a young girl who’s also displaying similar symptoms brought on by the drug Viper. Will Heston follow his gut? Or will he be deterred by the earlier incident?
