"Not Tomorrow Yet" is the twelfth episode of the sixth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on March 6, 2016.
While foraging in the woods, Carol kills a walker then painstakingly recomposes her appearance before making and distributing acorn and beet cookies to the children and her friends in Alexandria.
Rick calls a meeting and lays out the deal with the Hilltop and explains how the Saviors nearly killed Sasha, Abraham, and Daryl, and it would only be a matter of time before they found Alexandria.
Sleepless that night, Carol opens a diary which seems to be a list of the people she has killed: Ryan Samuels; Karen; David; Lizzie; approximately seven at Terminus; and seven Wolves.
As negotiator for the deal Maggie feels she has a moral imperative to see it through, though she suggests she takes a perimeter position keeping watch.
They plan to arrive at night, on the ruse that they are delivering Gregory's head to gain admittance to the building, and seize the room they believe to be the armory.
Operating in pairs, Rick and Daryl, Abraham and Sasha, Glenn and Heath, and Rosita and Aaron infiltrate the building with Michonne in reserve.
After committing his first human kill with Heath, Glenn finds a wall decorated with 20 polaroids of headshot wounds, reminiscent of a serial killer's trophies.
Tara asks Gabriel if he's still a priest, and confesses that she lied to Denise, that she'd been involved in an attack on another human community before, and didn't like it.
While Michonne wonders which of the corpses might be Negan, Rick's group stop a last Savior named Primo attempting to escape by motorcycle — Daryl's which had been stolen earlier.
Daryl is beating the man, demanding on where he got his bike when a female voice comes over the Savior's walkie-talkie ordering them to lower their weapons, saying that they have Carol and Maggie as hostages.
The critics' consensus reads: "Not Tomorrow Yet" tests viewers' patience with slow-building tension—and delivers with a powerful, action-packed ending.
