The charades in the name of bringing criminals to justice continue in episode 20 of "NCIS: Los Angeles" season 6, simply titled "Rage." More and more police detectives are joining the act to stop a white supremacist group capable of heinous crimes, whose notorious plans involve stolen nuclear material.   

To capture the bad guys from the inside, Callen takes on the identity of an inmate while Sam assumes the role of a guard. This time though, the new "NCIS: LA" episode will see Kensi on board the special mission. 

According to the synopsis for the episode, the special agent will be putting on tattoos to assume the identity of Callen's girlfriend. With Callen acting as a hard-edged biker bad boy who only recently got out of a cell he called home for six months, he will have to look like he so badly misses his smitten naughty girlfriend, so viewers can expect things to get all steamy between the two. They will have to pull off a pretty convincing performance and it looks like lip-locking will do the trick.

Of course, there will be an issue with Deeks watching this. Although the two will be kissing as a fanatical couple, it would not be easy for him to come to terms with that idea. Furthermore, those who have long wanted to see Deeks and Kensi hit it off will not be particularly thrilled to see this pretense unfold even further. Nevertheless, it's all part of the job. It remains to be seen if Deeks will feel that way, too.

For now, viewers can only hope that the special agents' acting chops will be enough to bring the bad guy down and wrap the case up into a pretty little package. 

"NCIS LA" season 6 episode 20 "Rage" will air on April 13.
