Will Trent Season 4 Episode 18: Be of Service

The finale doesn't just change Angie's life — it forces her to start over. After the long wait, Angie gives birth to a healthy baby girl, Edith, aka Edie. The moment is immediately undercut: on the way to the hospital, Angie and Seth are in a car crash, and while Seth initially appears unharmed, it quickly becomes clear he has been running on adrenaline. Moments after getting Angie safely inside to deliver their daughter, Seth collapses from internal bleeding and dies.

The loss leaves Angie in shock, in no position to care for a newborn. So Will does what he has to do: he takes a leave of absence and steps in to help raise Edie — a stark contrast to two years earlier, when his sense of duty tore them apart.

A montage spans the first full year of Edie's life: Angie remains at Will's home as she slowly pulls herself out of a deep depression, eventually reaching a place where she can fully care for her daughter again and, alongside Will, return to work. By the time the dust settles, the status quo has shifted in a major way — Angie, Will, Faith, Ormewood and Franklin head into the next season with a new dynamic: Faith leads a joint APD-GBI task force targeting a sex trafficking ring, and the imminent arrival of a new deputy director looms over the GBI.

The finale trades its procedural spine for a year of grief and repair. Seth's death — the crash, the adrenaline, the internal bleeding — lands minutes after Edie's birth, and the season ends inside the year that follows: Angie's depression and slow return, Will's leave of absence and co-parenting presence, and the team's new shape. The closing status quo is deliberate: Faith steps up to lead a joint APD-GBI task force against a sex trafficking ring, Amanda's chair stays empty for a new deputy director, and Angie and Will — family long before lovers — raise Edie together.
