"Heads Up" is the seventh episode of the sixth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on November 22, 2015.
He catches up to her in a restaurant, and despite her holding a gun to him, Glenn manages to convince Enid to accompany him back to Alexandria.
Tara helps to dispatch walkers while Rick, Tobin, and Morgan pull Spencer back inside Alexandria.
Later, Morgan discreetly meets with Denise, acting as Alexandria's doctor, and tells her he needs her help to treat somebody injured.
Morgan leads Denise to the lone Wolf he had secured in one townhouse, but his actions are witnessed by Carol, who follows them inside and demands to see who he has captured.
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.
The critics' consensus reads: "With "Heads Up," The Walking Dead offers the resolution to a major cliffhanger, but with frustrating results.
"[1] Matt Fowler of IGN gave it a 7.0 out of 10 and wrote in his verdict: "The best parts of "Heads Up" were definitely the beginning - which finally cleared up the whole Glenn debate/debacle - and the very end when the building came crashing down, breaking the town's big barrier.
