NCIS: LA kicks off another season this Sunday with the return of JAG stars David James Elliott as Navy Capt. Ahead of the NCIS: LA premiere, ET spoke with Bell about reprising her beloved JAG character after 14 years, what it was like reuniting with Elliott and if Harm and Mac will give their failed romance another go. I actually reached out to [NCIS: LA showrunner R.] Scott [Gemmill] a couple months before it finally did happen and I hadn't talked to him in forever. When we see Harm and Mac in the finale of NCIS: LA, they're only video conferencing together. NCIS: LA premieres Sunday, Sept. 29 at 9:30 p.m. ET/PT on CBS.
