Pauley Perrette has been playing the role of endearing forensics specialist "Abby Sciuto" on NCIS for ten seasons now, since the show's premiere in 2003. As cherished as her quirky character is, the show doesn't explore into her past very often; however, viewers will have a rare opportunity to delve into her past as young actress Brighton Sharbino portrays a childhood Abby.
Perrette brought the young Sharbino along with her to ET for her first ever interview to talk about her upcoming episode as Abby on NCIS.

"We really don't know much about Abby's past. It's the character with the least past development that we know of," Perrette said. "So, I was really, really super excited when they were like, 'We're going to show Abby as little.' I was like, 'Yay! Who's going to play her?'"
Perrette revealed that she and Sharbino struck a kinship when they were filming and she would come to the set on her off-days just to spend time with the young actress. While it was her first appearance on NCIS, Perrette said Sharbino did an excellent job of portraying her character's young counterpart.
The young actress has previously appeared on a few shows, including the Hannah Montana and The New Normal and will have two films coming out soon. She is the younger sister of The Touch regular Saxon Sharbino, whom she is determined to surpass in Twitter followers.

As the crime drama's current rate of success, we may see Sharbino for many flashbacks to come, as the show is thriving in its tenth season and posting impressively high numbers in the ratings.
Perrette attributed the show's continual success to its analogous relationship to life with the various elements of action, humor, and drama combined in every episode. If anything, she assesses, people love the characters.
"Also, it's the characters," the 43-year-old actress said. "It's these characters that people feel like they know; they feel like they're their family. In between Tuesday to Tuesday, they're like, 'I wonder what those goofballs are up to.' You miss them. I miss 'em. I want to see what's going on."
