S6E7 · Heads Up

After being knocked off the garbage dumpster by Nicholas' corpse, Glenn crawls under the dumpster to evade the walkers that surrounded it. Time passes, the walkers disperse, and Enid finds Glenn. In a nearby store, she explains that she fled Alexandria when the Wolves attacked it, and before Glenn can learn more, she runs off.

In Alexandria, Morgan is forced to tell Rick, Michonne, and Carol that he let the captured Wolves escape. Morgan justifies his actions by reminding Rick that he previously spared Morgan's life, and that while he wanted to kill the Wolves before, he believes people can change. Rosita gives knife lessons to a group including Eugene, while elsewhere Carl provides handgun lessons to Ron, but refuses to allow Ron to use live ammunition. Ron sneaks into the armory to obtain cartridges for the gun.

Glenn discovers the body of David and his note to Betsy, and decides to chase after Enid. He catches up to her in a restaurant, and although Enid holds him at gunpoint, Glenn convinces her to accompany him back to Alexandria. En route, they find some balloons that they use to distract walkers to keep the way clear.

Rick assesses the damage from the Wolves' attack, and finds a section of wall where blood is dribbling from, and starts working to re-enforce it, aware his hammering is luring more walkers to the walls. Tobin joins Rick to help with the repairs, admitting to Rick that their group brought many changes to Alexandria but the remainder of them are adapting and thankful for their help.

Spencer attempts to climb over the Alexandria walls to lead some walkers away, but ends up falling. Tara helps to dispatch walkers while Rick, Tobin, and Morgan pull Spencer back inside Alexandria. Spencer explains his actions as trying to follow what Rick had wanted to do earlier, but had excluded any of the Alexandrians from helping.

Later, Morgan discreetly meets with Denise, acting as Alexandria's doctor, and tells her he needs her help to treat an injured person. Morgan leads Denise to the lone Wolf he secured in a townhouse, but Carol witnesses this, follows them inside, and demands to see who he captured.

In the distance, the townspeople spot balloons rising above the walls, and Maggie realizes it is a sign from Glenn. Just then, the old church tower, which had been deteriorating for a long time, topples onto the wall segment that Rick and Tobin were trying to reinforce, destroying it.
