The long goodbye has started for NCIS actress Pauley Perrette. TV’s most beloved forensic scientist happily tweeted out that she has completed her last scene on the show, which airs May 8.

No details were revealed on the nature of quirky Perrette character Abby Sciuto’s last scene, but Sean Murray, Brian Dietzen, Emily Wickersham and Wilmer Valderrama evidently are present, judging from the tweet.

Producers have promised Perrette isn’t leaving NCIS after a decade and a half without a “special send-off,” according to executive producers George Schenck and Frank Cardea.

“We’ve known for some time this would be Pauley’s final season on NCIS and have been working toward a special send-off,” Schenck and Cardea said earlier to Deadline. “From day one, she has brought incredible passion and specificity to the role. Abby is a character that inspires millions of fans around the world, and all of us at NCIS are appreciative of Pauley for portraying her.”

CBS itself was equally effusive, calling Perrette and her Abby role, “a beloved actress and character.”

“Pauley has been a valued member of both NCIS and the CBS family for over 15 years,” said the net and CBS TV Studios in a joint statement. “While it’s never easy saying goodbye to a beloved actress and character, we respect her decision to leave at the end of the season. We are grateful to Pauley for all her contributions to the series and making Abby one of the most unique characters on television.”
