"Knots Untie" is the eleventh episode of the sixth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on February 28, 2016.

The Hilltop Colony is introduced in this episode, as well as many characters from the comic books, most notably Gregory, who is played by Xander Berkeley.

Jesus calmly explains that "knots untie, locks get picked, entropy comes from order," suggestive of a philosophy that seeks harmony over control.

Jesus reveals that while he was loose, he took account of the Alexandrians' armory and provisions, assessing their food supplies to be very low for his estimate of their population.

The group arrives at "The Hilltop Colony", a community built around Barrington House, a plantation taken over by the state as a living history museum.

A stockade was built with telephone poles from a nearby supply depot and other survivors brought trailers with them from a FEMA camp.

Later, Rick says that they came all this way for food and they're going to get it, but Jesus calls for patience as he works to convince Gregory that it'd be better to show some goodwill to Alexandria and build a relationship that could pay back in the future.

Other Hilltop residents are shocked as they watch Rick kill Ethan, prompting the other two traders, Andy and Crystal, to begin attacking as well.

Abraham, who became eerily still while being strangled by Andy during the fight, says that he is "better than alright" as Daryl helps him up; he smiles, seemingly having come to a decision in his personal life as Rosita's broken medallion is shown discarded on the ground.

The critics' consensus reads: "'Knots Untie' is an excellent, albeit unevenly scripted, foundation for the dangerous and degenerative societal clash it foreshadows.
