10 season 4 episode The Walking Dead
The episode is called "Silence the Whisperers". Overall, there were three main parts of this episode: attacks to communities and their ways of defense, improvement of relationships between three characters and Negan's escape.
The main background of all events in the episode was permanent attacks of "walkers" (zombies) to three communities: Oceanside, Alexandria and Hilltop. Characters assume that it is because of "The Whisperers" which is a big and dangerous group using walkers as their strategic advantage. Although Alexandria did good with defense, survivors in the Hilltop had been fighting with walkers for 2 days , but their walls have fallen eventually. The leader of Alexandria - Michonne, had sent reinforcements to Hilltop which repelled the attack and repaired the walls. Finally, Michonne was said that things at Oceanside are not better, but there is no more information about Oceanside in this episode.
Whereas Michonne was not in Alexandria, something horrible happened there. A girl, whose name is Lydia, was a member of "The Whisperers" before she realised that they are evil. Despite her attempts to show that her intentions are clear, some of the civilians of Alexandria do not trust her. Eventually it has represented into full hatred to her by three persons. They had tried to kill her at night by sudden ambush, but Negan saved her. However, Negan pulled one of attackers so hard that he killed her by accident.Therefore, people ask council to execute Negan, whereas the only person who is on side of Negan is Lydia. Council puts Negan to cage for a while to make a decision what to do with him.
However, Negan escapes from the cage by someone's help. People have a lot of questions for Lydia and she tells them that she is escape partner of Negan. Although it seemed to be truthful, Daryl knows that she did not do that, since he was watching her to protect her just in case. Finally, Negan escapes, people are on alert and nobody knows who to blame for all of that.
In conclusion, this was a great, full of action episode. The relationships between Daryl, Negan and Lydia have developed and Lydia has become more confident in her actions than ever. I think the next episode will be about details of Negan's escape and Oceanside defense against walkers.
