(And also includes a weird flashback involving Laurie Holden’s Andrea, somehow.)
But let’s just say that when Beta does discover what happened to Alpha, Negan had better hold on to his own head if he wants to survive the rest of the Whisperers War.
It doesn’t look like Beta and the other Whisperers’ response to Alpha’s beheading will be revealed very soon, since the next episode seems to be wholly centered on showing viewers what Michonne has been up to since heading out with Kevin Carroll’s Virgil with the goal of securing a bunch of weapons.
