It's not surprising that NCIS has seen some ups and downs in its run of more than 20 seasons, but one development that might have struck some viewers as particularly odd is Jennifer Esposito's Alex Quinn departing the show after just one season. Casting changes aren't exactly uncommon in a long-running series, with the NCIS season 22 cast and the original NCIS cast sharing exactly zero characters in common (McGee's been around so long, it can be easy to forget he didn't join until season 2). But Quinn is the only main character not to do more than one season.
