Rick: We can have a future.
Negan: I know I will.
Rick: Just give me… Give me 10 seconds so I can… I can tell you how.
Rick: Just give me 10 seconds for Carl.
Negan: Ten… nine…
Rick: Carl said it doesn’t have to be… It doesn’t have to be a fight anymore.
Negan: He was wrong. Eight…
Rick: No, no. He was right.
(Rick slits Negan throat with a piece of glass)
Negan: Look what you did. Carl didn’t know a damn thing…
(Negan collapses on the ground, Rick is walking away)
Rick (to Siddiq): Save him.
Michonne: Maggie! Maggie! (Michonne stops her from going after Negan)
Maggie: No, he can’t! No! No, he killed Glenn!
Rick: We have to.
