The Better Call Saul Secret That Was Hardest To Keep - Exclusive

Contains spoilers for Better Call Saul

Actress Rhea Seehorn is good at keeping secrets. As Better Call Saul's Kim Wexler, she has to be. The people behind Saul and its predecessor, Breaking Bad, have become quite adept at keeping both series' mind-blowing plot twists under wraps — remember, these are the same folks who filmed an entire movie in secret — and the cast is expected to follow suit. On Better Call Saul, not knowing what's going to happen next is half the fun.

That doesn't mean that staying quiet is always easy, though. Sometimes, it's all Seehorn can do to keep from talking. "The car accident, I kind of wanted to tell," Seehorn admits to Looper in an exclusive interview, referring to the third-season crash that put both Kim's life and her career in jeopardy. "They edited it so brilliantly. It's so jarring. I did want to tell people about that. But I couldn't."

In fact, Seehorn didn't even tell the people closest to her about what was in store. "I didn't even tell my fiancé. He knew that I didn't fly home after that episode, so I must have been in more episodes, but he didn't know if they were flashbacks after that. He didn't know if it was, like, is she in a coma for the rest of the season?" she says. "So, he jumped."

Another secret that the actress found hard to keep? Whether or not Kim would ever join Jimmy McGill (Bob Odenkirk) on one of his less-than-legal scams. Of course, by this point, we'd seen Kim serve as Jimmy's willing accomplice more than once, but back before the second season premiered, whether Kim or not would ever break bad — even just a little – was a serious question.

"I kept being interviewed before that season," shares Seehorn. "People were just like, 'Do you think she'll ever be like that? Do you think she'll ever do a scam?' I was like, 'I don't know.' So yeah, that was hard to keep secret."

The truth came out as soon as Better Call Saul season 2 started — the season premiere features an extended scene in which Jimmy and Kim rack up a huge bar tab while swindling an obnoxious investment baker. Less surprising? As with everything she does, Kim is an excellent con artist.

However, there's one big secret that Seehorn couldn't reveal even if she wanted to: what happens to Kim at the end of the series. See, while many Better Call Saul characters also appear on Breaking Bad, which takes place later in the timeline, Kim doesn't — leading many viewers to assume that she's going to meet a tragic end.

But don't ask Seehorn what's going to happen. She doesn't know either, although she does have some favorite fan theories. "I like the humorous ones.... Like, people talking about inserting her in Breaking Bad in like a weird Rashomon, Adobe-Photoshop-style," the actress says. "She's in the parking lot, waiting. Being in the back of Cinnabon with a hairnet on, you just never pan the camera over far enough to see her."

Otherwise, she says she doesn't worry about it: "I used to sort of spend a lot of energy worried, reading scripts in my bed for season one and two, and frantically skipping through them, trying to figure out like, oh, I live another day."

Better Call Saul's writers don't let the cast in on what's coming up until the scripts arrive, and adjust storylines while the season is filming, Seehorn explains: "Eventually, you just have to let it go and put your hands up. I decided a while back to not dwell on the actual specifics of how she goes out, if she goes out, in what state she goes out."

In fact, Seehorn says that the uncertainty makes her performance better: "I have to live in the present moment because... none of the characters have seen Breaking Bad. So, when I'm making decisions about how Kim feels about things Jimmy is doing, it's really good for me that I have to take it a page or a moment at a time, because she can't see into the future."

The ability to focus on what's happening in the current scene, and not in later ones, is actually one of the biggest lessons Seehorn has learned from her time on Better Call Saul. "Play what's happening now, not what's happening in the future," she says. "That's much harder than one thinks, but it is very informative for a scene."

In other words: Kim may or may not survive through Better Call Saul's finale, but by all indications, Rhea Seehorn is going to be just fine.

Better Call Saul airs on Mondays on AMC at 9 PM.
