When Myles gets ambushed and shot during a planned raid, the team comes to suspect that some DC political office leaked information to the media, allowing the terrorists to know they were coming. While they track down the people involved, Myles grapples with his close brush with mortality.
This episode includes examples of the following tropes:
- Bittersweet Ending: The FBI catches the terrorist they've been chasing, and Sue successfully talks Myles into seeking therapy for his trauma over being shot. However, one of Sue's informants, Malik, lost his life when the terrorist cell caught up to him, leaving behind his grieving mother.
- Bulletproof Vest: Myles is wearing one during the raid, which saves his life when he's shot. Nonetheless, it's noted that the bullet could still have killed him, and Myles complains of massive bruising.
- Dating What Daddy Hates: One of the FBI agents suggests that the lead terrorist's American girlfriend, Laura Greenley, became involved with him out of a desire to rebel against her father.
- Death Notification: After Malik's body turns up, Sue and Jack return to the young man's mother to break the unhappy news. She initially thinks they might have found him and begins sobbing when she hears the truth.
- The Dog Was the Mastermind: Downplayed; while confronting reporter Joe Harding, the team briefly meets an intern. She isn't the head of the terrorists, but she's involved with the leader and leaked the information.
- Endangering News Broadcast: Played With; the team suspects that the media was involved in the leak. They track the problem to a reporter named Joe Harding, who insists they can't blame him because he didn't release the information before the raid happened. However, it turns out that one of the interns at the paper is a terrorist sympathizer, leading Sue to chew Joe out about the importance of confidentiality.
- Enhance Button: A particularly egregious example; Tara tries to find clues about a terrorist's location based on a video he sent a news station. She enhances a barely visible spot of color behind a white curtain and comes up with a brightly-colored, easily readable neon sign for a diner.
- Feed the Mole: To figure out which office leaked the information, the FBI gives the offices a bunch of valid information and one unique piece of misinformation per office. Once they see which piece of misinformation becomes public, they'll know which office probably leaked the information about the raid.
- Friendship Moment: Myles is the person in the office least likely to get along with Sue in any given episode. After everything is over, she finds him having a panic attack on the stairs. She talks to him about the situation, urges him to see a therapist, and agrees not to tell anyone about his breakdown.
- Fuzz Therapy: The titular leak leads to Myles being shot during a raid (luckily, in his bulletproof vest). When he starts having a panic attack, Levi puts his head in Myles' lap to help him calm down.
- Like You Were Dying: A variant; Myles has to deal with nearly getting killed, and it ends up giving him PTSD. Sue, talking to him about it, says he'll probably never treat a raid the same way again. However, she adds that he should also never see a sunset the same way for the same reason.
- Outliving One's Offspring: Malik, one of Sue's informants, starts acting fidgety and goes missing soon after the raid. Jack and Sue go to his mother, who begs them to find her son. Midway through the investigation, Malik turns up, dead from a gunshot wound presumably inflicted by the terrorists.
- Pet the Dog: Joe Harding spends most of his scenes being hostile towards the FBI (though admittedly, neither of them is too fond of each other). However, when Sue mentions that Malik was killed because of the information he had on file, he offers his condolences.
- There Are No Therapists: Averted. Sue recommends Myles see a therapist to help cope with what happened to him, referring to admitting he needs such help as an act of bravery. Myles takes her advice; the episode ends with him walking into a clinical psychologist's office and saying he has an appointment.
