Fans may be used to seeing a bubbly Abby Sciuto, but in an upcoming episode of NCIS, she will show a different side.

In the April 29 episode "Shooter," Abby, played by Pauley Perrette, will take on a more dramatic role, according to the show's executive producer.

"We've got some really talented, gifted actors on this show and anytime we can put them into situations that stretch them a little bit, we look forward to doing that," Gary Glasberg recently told TVFanatic.com. "These last episodes for the entire cast gives them the opportunity to use some muscles that they don't get to use all season long."

NCIS Coming Back For Season 12   

He added: "My goal with these last episodes, and this is true of Season 12 as well, is to really focus on the team and get back to the basics, as they call it, of the stories and why people watch NCIS. The emotion, the characters...that's what these episodes will focus on."

The season 11 finale will also showcase a new side to one more character -- Leroy Jethro Gibbs. The character will have to deal with the loss of his father, Jackson Gibbs, played by Ralph Waite, who passed away in February.

"Well, it's definitely new territory for him and, honestly, I'm really anxious to see how Harmon plays it," Glasberg said. "We're prepping it right now and we start shooting in a few days and I'm really excited about it."

The NCIS season 11 finale will air on Tuesday, May 13 at 8/7c on CBS.
