‘It makes me cry’: Missy Peregrym opens up about FBI’s shocking episode that will change Maggie forever

CBS’s hit procedural series FBI delivered one of its most shocking moments yet in the March 16 episode, leaving fans reeling. Actress Missy Peregrym, who plays Special Agent Maggie, faced the emotional challenge of portraying her character’s first personal tragedy on the show: the death of her sister, Erin. Peregrym has now broken her silence, revealing just how intense and transformative filming the episode was for her and the story.




Peregrym described walking into the key scene “not knowing what my body’s going to do,” emphasizing the immediacy of the moment. She didn’t see the actress playing her sister beforehand, wanting her reaction to remain authentic when discovering Erin’s fate. The critical sequence was filmed in a single take, adding to the realism and emotional weight. The storyline, which had been adjusted from its original script, aimed to capture the full depth of grief and fear without offering a neat resolution.




This episode marks a turning point for Maggie. Peregrym explained that the loss is not something her character can simply move past—it fundamentally alters how she approaches both her personal life and her work. After eight years on the show, this moment forces Maggie to navigate a completely different emotional landscape. The show, typically procedural, allowed her to explore vulnerability and grief on a level rarely seen before in the series.




Despite the devastation, Maggie must continue with her responsibilities at the FBI, highlighting the tension between personal loss and professional duty. Peregrym noted that the show’s writers trusted her to handle the material sensitively, and the result is a portrayal that resonates with anyone who has experienced sudden tragedy.

For viewers, it’s a reminder that procedural dramas can carry real emotional stakes, and that the characters they follow are shaped not just by the cases they solve, but by the losses they endure. The episode has left fans discussing how the FBI is evolving, with Peregrym’s performance drawing praise for its authenticity and emotional depth.
