NCIS season 21 cast (predictions)
It has not been confirmed that Wilmer Valderrama is leaving the show, so it is more than likely that Nick won’t do anything that affects his career and, most importantly, his life. But it will be a great arc to see as we learn more about him. Other cast members expected to return include:
Rocky Carroll as Director Leon Vance
Sean Murray as Agent Timothy McGee
Katrina Law as Agent Jessica Knight
Diona Reasonover as Kasie Hines
David McCallum as Dr. Donald “Ducky” Mallard
Gary Cole as Agent Alden Parker
