After Jessica Logan kidnapped Jiya and brought her to one Rittenhouse's bases of operation, Carolyn Preston told Jiya she'd have a lot to learn, and needed to be well rested. She was told to take a pill to help her sleep, or Doug would force her to take it. She refused, and Doug forced the pill into her mouth.
Later, when Doug was checking to see if Jiya was sleeping, he found that she had supposedly fallen asleep off of her bed. He came into the room to help her onto the bed, but Jiya wasn't actually asleep and ended up strangling Doug with the sheets.
