I have to say that Kiksuya, is actually one of the most beautiful and poignant episodes of Westworld ever. For much of the series, Akecheta has been a background character at best. We've seen him through flashback apparently terrorize Maeve and her daughter, as well used as be utilized as a tool to get Logan to encourage his father to invest in the park itself. This week, Akecheta moves from a silent background character to one with a deeply compelling story of moving from being a simple robot to a sentient being trying to understand his world and to deal with the loss of his family and the woman that he loves.
When we last left William, he was laying on the ground injured from his interaction with Maeve. William is crawling in the dirt towards the lake, determined not to die in the dirt. Akcheta tries to communicate with him in Lakota, but of course, William never bothered to learn the language. Akcheta switches to English and makes it clear that he remembers him. William is the brought to the village by Akecheta. William is naturally curious to know why he isn't being killed out right and is informed that death is too good for him. I have to say that after watching the numerous horrors he has inflicted upon the hosts, I wholeheartedly agree.
Maeve's daughter watches the exchange between Akecheta and William and is clearly terrified. Akecheta approaches her cautiously, worried that she is afraid of him but as it turns out, Maeve's daughter has retained enough of her memories to realise that the one to fear is actually William and not in fact Akecheta. Akecheta tells her that she has nothing to fear from William now and that he will protect her as he always has. In a flashback, we see Maeve's daughter hand Maeve a bloody rock with the maze painted on it, claiming that it's a warning from Ghost.
The flashback changes and this time, it looks back into Akecheta's life in the park before it opened. Akecheta led a peaceful life surrounded by those he viewed as family along with his wife Kohana. This life however was not to be and came to an end the day he discovered the first massacre at the park - the massacre where Delores not only killed a lot of hosts but Arnold. It seems that this was Arnold's failed attempt to ensure that the park didn't open. This is where Akecheta sees the maze for the first time and it makes an indelible mark upon him. Akecheta doesn't even have a chance to process exactly what has changed before he is brought in for reprogramming and the life he knows is ripped from him. Akecheta goes from being a peaceful man, moving through the world and loving his family to a man who rampages and murders i.e. everyone except what he calls newcomers (read: humans)
Akecheta lives out the cycle that he is reprogrammed to perform but his mind remains somewhat troubled. It is a chance meeting with Logan that sets him on a path to find a way out of the park. Logan, as we know, had been banished by William and Akecheta find him, sitting naked and babbling to himself about wanting to find the door and the real world. Akecheta pauses long enough to give Logan a blanket to cover his nakedness, promising that his kind would find him soon; however, Logan's words become the key to Akecheta's quest. Now Akecheta knows that the life he is leading isn't right and that there's a way to escape. It is then he remembers his wife Kohana.
Back in headquarters, having delivered Maeve to the lab, Lee is desperate for her to survive. Unfortunately, the tech's only real concern is to get as many control units as possible from the huge pile of dead hosts which are a result of the awakening and high rate of violence. Lee is forced to argue that Maeve is different and can control the hosts with her thoughts, before beging the tech to look at Maeve's scans. This is enough for the tech to start working on Maeve and it's a gruesome sight given that we know from Bernard's visit to the cradle that hosts do indeed feel pain.
Now determined to find a way out of Westworld, Akecheta heads to the valley beyond. The valley as it turns out is a huge canyon dug into the earth. There seems to be a sort of elevator built in. Akecheta interprets what he sees as a path to escape but he decides not to leave until he can reunite with Kohana, even though she no longer remembers him. Akecheta returns to Kohana's village and he kidnaps her in middle of the night. They ride the horse together and Akecheta pauses long enough to wash off the makeup - clearly a visual signal that he is putting aside the life foisted upon him by the rewrite. For the first time since massacre, Akecheta is himself again. With his makeup gone, it's time to approach Kohana again and let her know that she doesn't need to be afraid. Akecheta moves slowly and cuts the ropes holding her hands and she backs away in fear. Slowly, Akecheta approaches and this time, he places her hand over his heart and says, "take my heart when you." This is the phrase that the lovers would say when they separate. It takes a moment but Kohana responds, "Take mine in its place." This time, when Kohana looks into Akecheta's eyes, she knows him as her husband.
Now that the lovers know each other for who they are, it's time to head towards the door, which unfortunately is buried under the canyon. Akecheta promises Kohana that they are going someplace their memories will be safe. Unfortunately, the techs catch up to Kohana while Akecheta is off gathering food. Akecheta watches in horror as Kohana is loaded into a truck and taken away, as the techs wonder how she managed to get so far away from where she is supposed to be. Akecheta returns to Kohana's tribe believing that this is where the techs would have taken her, only to find a stranger in her place. Just like Maeve's daughter was given a new mother, Akecheta now finds a pale substitute in place of his love.
Having struck out at the tribe, Akecheta wanders across Westworld looking for Kohana, hyper aware of his own vulnerability as he passes through places with extremely hostile hosts and humans. He is desperate to remain alive, fearing that death will mean that he will be erased and once again forget about the life he had with the woman he loved. After clearly barely surviving another attack, he runs into Maeve's daughter, who greets him with kindness and water. Akecheta believes that this is the first time that he has been seen for who he really is.
Having failed to find Kohana on his long journey, Akecheta decides to return to her village and this time he meets a woman whose son has been replaced. Akecheta learns that the people have begun to speak about the place down below. Akecheta finally realises that Kohana will not be found in Westworld and the only way to see her again is to die. This is similar to the revelation Maeve had about dying and increasing her power and awareness. Akecheta allows himself to be killed by a guest and ends up in the lab for the first time in ten years.
