On May 12, worlds collide once again when CBS' NCIS: Los Angeles finds itself in harm's way – Captain Harmon "Harm" Rabb's way, to be more precise – as David James Elliott reprises his popular JAG role for an upcoming story arc – but the crossover doesn't stop there. One week later – on May 19 – Catherine Bell (Good Witch) will reprise the role of Lieutenant Colonel Sarah "Mac" MacKenzie in the long-running CBS series' season finale.
In Elliot's first episode "The Guardian," the NCIS team uncovers ISIS sympathizers aiming to plan an attack on U.S. aircraft carriers. The terror threat results in Callen (Chris O'Donnell) and Sam (LL Cool J) working directly with Harm, the XO Captain on the USS Intrepid. Bell's Mac enter the scene the following week, when Hetty (Linda Hunt) reaches out for assistance in preventing an attack on US aircraft carriers.
"Catherine's 'Mac' was a strong, smart woman who held her own, and then some, in a male dominated world. Her character paved the way for other strong female leads. Not only is it great to be working together again as friends, but to be able to write for Catherine and have her same character interact with our NCIS: Los Angeles characters now, that's wonderfully surreal. It feels like everything has come full circle."
