Diane Neal realized just how avid NCIS fans are soon after her initial appearance on the show.
"After I did that first episode, I'd be walking down the street and people would [say], 'What's going on with Tiva?' and I was like, 'Why is everyone talking about a pair of sandals?'" she says. Neal soon learned that "Tiva" is the shipper name for fans who want to see a Tony DiNozzo-Ziva David coupling.
