"You talk about Mark Harmon, Mark is someone that leads with kindness and his energy is beautiful. We have quite a bromance going on, him and I. But from the top, down, I think it's the people. The fact that people still love coming to work," he told in an interview with Entertainment Tonight.

"NCIS" season 17 airs Tuesdays on CBS.
