G. Callen's Best Moment In NCIS: Los Angeles Season 8

Though it takes place in the same universe, "NCIS: Los Angeles" is a very different beast from the original "NCIS." As such, it makes sense that the Los Angeles office's Special Agent in Charge is a far cry from the original show's contemplative and gruff Leroy Jethro Gibbs (Mark Harmon). Though G. Callen (Chris O'Donnell) knows Gibbs and has his seal of approval, the L.A. hotshot is more of an action hero type, and his past is somehow even stranger than his colleague's: Callen is a former spy with strong familial ties to Russia and Romania, and his past is so mysterious that he doesn't even find out his full first name until the tail end of the show's Season 7. (It's Grisha.) 

Because of his characterization, Callen isn't exactly short of cool moments in the show, from catching bad guys to digging into the mysteries of his own, complex past. But what's his absolute best moment in "NCIS: Los Angeles" Season 8? Let's find out!

Callen is one of the rare characters whose love life has actually received a fan nickname. His complex romantic relatinship with longtime acquaintance Arkady Kolcheck's (Vyto Ruginis) daughter, Anna (Bar Paly), is affectionately known as Callanna, and since Anna becomes more and more involved in the NCIS team's business in Season 8, it's only natural that one of the season's most memorable moments involves the two on official business.

In "Queen Pin," Callen and Anna intend to have a day off and focus on their relationship, but are called in to deliver a prisoner called Ahmed Han Asakeem (Sammy Sheik) to a destination. Determined to make a day out of it regardless, the pair spend a portion of the drive practicing their musical chops — by dueting "You're the One that I Want" from "Grease," of all things. They clearly have a whale of a time, but Asakeem remains unimpressed and likens the pair's singing to torture.

Many fans have mentioned this brief moment of fun as a personal favorite. "Lmao Callen and Anna singing 'Grease' songs," @OMGLEZY tweeted. "My favorite part of this episode so far is Anna & Callen singing to Grease in the car! Love it!" @musiclove18 agreed. "A fun drive," @Tomoko22131931 wrote, complete with a bunch of musical and car-themed emojis. 

Given that Callen is generally more of a cool, mysterious guy than a fun goofball, it's clear that this moment of true levity holds a special place in fans' hearts.
