Start picking out onesies, Densi fans. NCIS: Los Angeles's Deeks and Kensi have babies on the brain.

Over the last three seasons, Densi have gone from flirtatious partners to a live in couple. When Hetty's (Linda Hunt) team is faced with a trying case in "The Seventh Child," the pair will start to wonder what their future holds.

"Callen (Chris O'Donnell) and the team try to save a child in imminent danger who has been brainwashed by a terrorist cell," CBS said of the March 21 episode. "Also, Deeks (Eric Christian Olsen) and Kensi (Daniela Ruah) discuss having children."

Is that the pitter-patter of tiny feet we hear? Deeks and Kensi have never had an onscreen discussion about taking on the titles of Mom and Dad, but the topic has been circling the couple since last season. It wasn't that long ago that Deeks applied to become a mentor, and Densi made fans' hearts melt as they serenaded a newborn in "Core Values."

Whatever the outcome may be, we're excited to see the beloved 'ship setting a course for the future. NCIS: LA writers are experts at keeping Densi from overshadowing the team's main storylines, and it's a careful balancing act that makes the pair's scenes all the more special.

Find out what's next for Densi when NCIS: LA air Mondays at 10 p.m. ET. Click below to see a preview for the March 14 episode, "Exchange Rate."
