Recap of FBI Season 8 Episode 17
The last episode, “Shahadah,” was very stressful for OA. The team found the body of a psychiatrist. The clues led them to a mosque where OA sometimes prays. He had to investigate the Imam, which caused a lot of pain for him.
The team learned the Imam was innocent. He was actually trying to protect a woman named Aliyah. Aliyah was hiding in fear. Even though OA knew Aliyah was scared and was not the real criminal, he had to arrest her for keeping evidence from the FBI. The episode showed the hard choices agents have to make. Now, in Episode 18, the focus moves to Maggie and a completely different kind of threat involving a mother and child.
