There will be sort of a crossover between "NCIS: Naval Criminal Investigative Service" and its spin-off "NCIS: Los Angeles" when both take over the Tuesdays night this Fall. Pauley Perrette, who portrays the goth agent Abby Sciuto, will guest star in the second episode of "Los Angeles".
Executive producer Shane Brennan announced Friday, July 31 during TV Critics Association tour that Abby will have a "fun little cameo" in the new series, helping the unit in solving a case. Previously, Agents G. Callen (Chris O'Donnell) and Sam Hanna (LL Cool J) have made appearances on the original "NCIS" for two episodes, as means of introduction.
Additionally, Brennan also revealed a new "Los Angeles" character which they had kept hidden. Matthew St. Patrick, known as Keith in "Six Feet Under", will be a "former special ops guy who actually gets deeply involved in the case and may or may not be a bad guy."
"NCIS" and "NCIS: Los Angeles" will air back to back on September 22 and below is the new joint promo.
