Brian Dietzen, who plays Jimmy Palmer on NCIS, also spoke with CinemaBlend recently, and he only had good things to say about Reasonover’s addition to the cast, simply stating that changing “the ingredients” of a show will inevitably result in “the whole thing” changing.
Diona Reasonover did tease that some characters will struggle with Kasie replacing Abby in their own ways, so NCIS will clearly address the change rather than just going on as if Abby had never been around.
The transition that could have been very difficult for everybody went down without the newcomer feeling a great deal of pressure from the cast, crew, or even the fanbase, which is fiercely loyal after the better part of two decades following NCIS.
