NCIS showrunner Steven D. Binder teases a surprising resolution to Alden Parker’s hallucinations of Lily. The CBS procedural continues following the Major Case Response Team, now led by Parker (Gary Cole), who took over when Leroy Jethro Gibbs (Mark Harmon) chose to depart the Naval organization. The young character known as Lily first appeared in the NCIS season 21 finale, “Reef Madness,” where she was imagined by a gravely wounded Parker. Lily has since reemerged in NCIS season 22, but her identity and connection to Agent Parker largely remain a secret.
