FBI Fan Favorite Missy Peregrym Returns After Maggie’s Absence Following a Tragic Death

Missy Peregrym is back on FBI as Maggie, and the show does not pretend everything is fine. After a brutal twist that took Maggie off the board, she returns in the Monday, March 30 episode looking like someone who has done the work, knows it is going to hurt anyway, and is choosing to suit up.

So, what happened and where are we now?

• Earlier this month, Maggie’s first-ever collar on the show — serial slasher Ray DiStefano (Matthew Rauch) — resurfaced and kidnapped her sister, Erin (Adrienne Rose Bengtsson). Maggie chased him down, only to find Erin dead in the back of his truck. DiStefano didn’t make it out alive either.
• That loss sent Maggie on leave. In her return episode (March 30), she tells SAC Isobel (Alana de la Garza) she has been in counseling, actually let herself feel it, and got a professional sign-off to come back. Isobel reminds her this is eerily similar to the script Maggie used after her husband died — same words, same armor — and makes clear it’s her call to approve Maggie’s return to the field.
• Maggie’s partner OA (Zeeko Zaki) is thrilled she’s back. Isobel quietly asks him to keep an eye on her. OA later checks in anyway, makes it clear he would have regardless, and Maggie admits being back is tough but insists she’ll be OK.

The character beat that stings

FBI leans into the continuity here: Maggie has been through catastrophic grief before, and the show is honest about the muscle memory that kicks in. She believes she got as much justice as possible for Erin, but the point is not neat closure — it’s that she’s choosing to move forward while still in pain. That’s heavier than this franchise usually lets itself be, and it lands.

Missy Peregrym is not leaving — and she has thoughts about the story

Peregrym, 43, has no plans to walk away after Maggie’s loss. She told Deadline she sometimes wonders what it means to do a procedural that parades humanity’s worst every week, but this arc clarified the why for her: showing how people put one foot in front of the other after something unthinkable.

We’re not a drama where we sit around in our underwear and chat on the couch. We’ve got to get back to work.

She says that was the challenge the writers had to solve: after going this far with Maggie’s story eight seasons in, what does getting back on your feet actually look like on a show that has to keep moving? Peregrym says the team is addressing the reality of that grief the best way a procedural can. She was nervous to go that deep, but now finds it interesting to play — picking her moments to show the cracks, then flipping back into mission mode. It almost feels like doing a new show again, which she calls a gift.

FBI airs on CBS Mondays at 9 p.m. ET.
