Pauley Perrette and Mark Harmon portrayed coworkers with a father-daughter relationship on NCIS for 15 years. When it was announced in 2018 that Perrette would not be returning to the show, fans assumed it was to pursue other projects. However, she only appeared in one series since leaving and had a feud with Harmon, who brought his dog to set and continued to do so after it bit a crew member.
