- The Season Finale "Descent" by the end. Sidorov has captured Sam and Deeks and is using Electric Torture on Sam to learn if Quinn - Sam's wife Michelle - is a federal agent. Then it goes From Bad to Worse; Sidorov goes and starts on Deeks using a dentist drill. All Sam can do is watch as Deeks screams in agony.
- It gets even worse if you look at it from Sam's perspective: he pretty much admitted earlier in the episode that he doesn't respect Deeks to his face. Not only did Deeks save his life from drowning, but now all he can do is watch and listen to Deeks' screams - which are echoing - and hope that the man that he said he didn't respect can find it in himself to fight through the agony and protect the woman he loves.
- We see the aftermath of their torture in "Ascension". Deeks' mouth is covered in blood and when he awakes, he's practically begging Kensi to get him out of there.
- Harley Hidoko was a promising new cast member to the team, with good chemistry with others and especially Sam. So when she goes missing in the season finale, "Ninguna Salida", the cast can only hope that it's nothing serious - but as the intro to the episode and the aftermath shows, she was caught by the Mexican cartel, tortured with someone cruelly cutting out her tongue, and then burned alive until nothing but ashes and bone fragments remained. Needless to say, this doesn't help the team's opinion of the sheer dangers of the unsanctioned operation.
- "Mother" has probably one of the most violent corpses in this spin-off series, when Kensi and Deeks stumble into finding the Victim of the Week sans his hands and entire lower body. All from a traitorous asset trained by Hetty herself who is hellbent on blaming her and everyone involved with her for ruining his life.
- "The Sound of Silence" has the LA team investigate the injuries of a Navy officer in Seal Beach, which turns out be caused by microwaves. Like the attacks on American and Canadian embassies in Havana, being affected by one can make you dizzy, nauseous and at most cases, can cause harm to your hearing. And then it gets turned on the team during the climax...
- "Imposter Syndrome" has a hacker using an amazing "deepfake" program to not only perfectly mimic any of the team's voices but even creates a live video chat of Fatima that has the team fooled. While the hacker is caught, his tech is still out there, leaving the team to worry how much damage could be done by someone brilliantly copying others like this.
