As fans anticipate the ending ofNCIS: Los Angelesafter its 14-year run,LL Cool Jadmits he also wanted to feel an element of surprise.

The first of the two-part finale aired May 14, leaving fans to wait a week for the final episode on Sunday, May 21, which the series teased as “earth-shattering” in a recenttweet.

Rather than reading the last script of the series, LL Cool J said he chose to focus on giving the best portrayal of his character, Senior Special Agent Sam Hanna.

“I just felt like I was in the zone of, I just wanted to do the work,” explained the actor, whose real name is James Todd Smith. “I mean, I knew where I was coming from, I did my homework, but I just didn’t want to read that last scene and get into that.”

“The experience was amazing because you mature, because you grow as a human being, because you make new friends, new relationships, all of that, right?” he explained.

“I think the only thing I’ll miss really is just the day-to-day working with all the men and women, all the people on the set,” he shared. “It was just so many relationships — you know, we’re talking about 14 years, so I’ve seen people have kids, babies go to college, I’ve seen marriages, I’ve seen everything in between, and so I will miss working day to day with people who became friends.”

He also recalled the exact moment when filming wrapped — and how reality set in for the cast and crew.

“It was amazing. You know, I mean this is 14 years later,” he noted. “Normally they’ll be like, ‘Alright, that’s an episode wrap,’ but this was an episode wrap and a show wrap and a series wrap. It was big, it felt big, but it felt like we accomplished something.”

“I know everybody’s got feelings and there’s a melancholiness on some levels, but you know, we made a huge accomplishment,” he continued, emphasizing the fact thatNCIS: LAis now the longest runningNCISspinoff.
