For more than a decade, NCIS: Los Angeles fans have watched Daniela Ruah and Eric Christian Olsen bring Kensi Blye and Marty Deeks to life with a chemistry so natural, it almost feels unscripted. Their banter, their warmth, their emotional depth — it’s all become a cornerstone of the show’s identity.
But behind that seamless dynamic lies a fascinating real-life twist: the actors are actually in-laws. Ruah is married to Olsen’s brother, David Paul Olsen — a detail that makes their on-screen romance even more unique in Hollywood.
So how do they really feel about playing one of television’s most beloved couples while sharing a real family connection?
Family First — On Set and Off
Both actors have said that their close relationship makes everything easier, not weirder. Instead of awkwardness, there’s trust — the kind that only comes from knowing someone deeply and personally.
Ruah has explained that the family bond enhances their performances, allowing them to “go there” emotionally in ways that feel safe and grounded. Olsen has echoed that sentiment, noting that their mutual respect eliminates any discomfort that might exist with another co-star.
Building a Partnership Fans Can’t Get Enough Of
Kensi and Deeks’ romance didn’t ignite overnight. It unfolded over seasons — subtle glances, playful teasing, moments of vulnerability — evolving into one of the most stable, heartfelt partnerships in the NCIS franchise.
The actors credit their chemistry to long hours rehearsing, refining dialogue, and continually pushing each other to deliver more authentic performances. Their real-life connection simply provides the foundation.
The Balance Between Real Life and TV Love
Working closely with a family member could create complications, but both stars have mastered the balance. Off-screen, Ruah and Olsen spend weekends together with their spouses and kids. On-screen, they switch seamlessly into character.
Ruah once joked that the only time things get strange is when she remembers her husband is the stunt double stepping in for Olsen during tense action sequences — a reminder that the NCIS universe is truly one giant family business.
Why It Works
At the heart of everything is trust. Trust that the other actor is committed. Trust that their family bond will never interfere with professionalism. Trust that their characters’ love story is worth telling — and telling well.
And fans can see that. It’s what makes Kensi and Deeks believable, relatable, and endlessly lovable.
A Legacy Beyond the Screen
As NCIS: Los Angeles continues to live on in fan discussions, rewatches, and streaming platforms, the partnership between Ruah and Olsen remains one of the show’s greatest strengths.
Their relationship — part family, part friendship, part artistic collaboration — is a rare Hollywood gem. And it’s the reason Kensi and Deeks are more than just characters. They feel real.
A romance born in the writers’ room, strengthened by the actors’ bond, and cherished by millions.
