When Niki and D. L. are revisited in "Parasite", D. L. confronts Jessica about the picture of Nathan Petrelli Niki left on his pillow. Apparently, Niki "overcame" Jessica for a short period of time and planted the picture without Jessica's knowledge. He questions her about what Linderman is making her do with Nathan, and she explains that there's nothing to worry about. After kissing her, he turns around and the smile he had on his face drops into a frown indicating that he's still suspicious.
