"What I heard is that there will be a character leaving at the end of this season, or towards the end of this season," Daniela Ruah reveals to us. "That's what I've heard. I don't know who it is. It might be me! Who knows?"

It seems that even the main cast does not feel safe about the future of the show. According to LL Cool J who plays Sam Hanna, NCIS: Los Angeles Senior Special Agent; he needs to make it out of season 5 alive first before he can be certain of his character's future.

"I want to get through this season, and then we'll get to those other episodes," he says. "From what I hear there's some cast members that might not make it through this season. Let's deal with that first."

"This season you're going to see a lot of shockers," LL spills. "We're going to throw curveballs at people and they definitely aren't going to see them coming."
