John Murphy first meets Emori in Rubicon while searching for the City of Light in the Dead Zone during the second half of season 2. Both outcasts for two totally different reasons, there was a spark between the two of them from day one, when Murphy first offered her some water. In the Dead Zone while travelling, Murphy learns that Emori was cast out for being a freikdreina; a mutant. She bravely shows Murphy her disformed hand, explaining that her parents saw her as a stain on the bloodline for it. Murphy doesn't see it as such, though, and tells her he thinks it's badass. Despite calling him a liar, Emori is smiling.
However, Emori ends up betraying Murphy, Jaha and the rest of the group travelling. Before knocking Murphy out, Emori whispers something to Murphy. After she leaves him and he comes to, he still remembered the words Emori said to him and still wants to trust her instructions of "due North" despite her betraying him earlier.
Due North proves to be correct and Murphy and Jaha end up where they had planned to be. It isn't until after Murphy gets locked in the Lighthouse Bunker for 86 days at the beginning of season 3, does he see Emori again. After being released from the bunker, Murphy is distrustful of Jaha and refuses to join him on the approaching boat. Upon seeing Emori, who says to him "John, I don't believe it" Murphy changes his mind and climbs aboard to join Emori.
Later in season 3, the pair are seen thieving from travellers. They argue about what their next step should be, and part ways. Although Emori surprises Murphy and reappears, saying she won't go until she can convince Murphy to go with her.
Murphy is then captured by Ontari and becomes her flamekeeper. In Polis, in Demons, Murphy runs into Emori again and they reconnect. Unfortunately Emori ends up taking the City of Light chip which leads Murphy hesitant to destroy the box containing the chip and everyone from the City of Light's memories.
After defeating A.L.I.E., Murphy runs into Emori's arms and hugs her tightly.
In season 4, they are seen scavenging together and Murphy convinces Emori to travel to Becca's lab with him and his people. At Becca's lab, they need a test for Nightblood. Blamed for lying about the true identitiy of a hostage, Emori is subjected for the test. Murphy screams at Clarke and fights the restraints on his wrists as they take Emori away from him. He begs Clarke to spare his life and claims he loves her. Clarke assures him that Emori will be fine, before leaving. She ends up not being able to go through with hurting Emori and injects herself. Murphy is released and is seen helping Emori.
They stay back with Raven while the others go to Polis. They grow closer despite Emori being worried that his people won't come back for them before Praimfaya hits. Murphy reassures her and says to her "who needs food when you have love", which seems to do the trick for Emori. They kiss and it is assumed they sleep together again.
In The Chosen when all of Skaikru are being rounded up so they can select their "one hundred" people for the bunker, Murphy worriedly asks Niylah if she's seen Emori. When he finds Emori he makes sure she's okay. A spur of the moment decision takes him and Emori back to Becca's Lab alongside others who will eventually become Spacekru. Both Murphy and Emori make it to space together and are alive at the end of season 4.
Though their relationship journey is not the most stable-they broke up during the time jump between season 4 and season 5 for 6 months-they still manage to prove their love and affection for each other in the end. When Murphy is injured at the end of season 5, in Damocles (Part 2) and it seems he won't be able to make it to the dropship in time, Emori refuses to leave his side, ignoring his pleas to leave him to die, instead telling him "then I guess we're both going to die, because there's no way in hell I'm leaving the man I love behind", confirming that despite their breakup, she still loves him.
In season 6, Murphy even goes so far as to propose marriage to Emori in The Old Man and the Anomaly. He asks her if she can "love him forever" and produces two mind drives that allows them to become Primes; the ability to live forever. Emori is shocked and her reply is interrupted by Josephine in Clarke's body. Later, when Murphy's life is endangered, Emori answers his proposal with "my answer is yes". She tells him that she'll love him even if they die today.
In season 7, Murphy and Emori are acting as Primes (siblings, Daniel and Kaylee) and get to live in the Sanctum Palace together. They are still going strong and Murphy is very caring towards his fiancé. When Emori gets sick and says to Murphy, "you wanted forever", he replies "still do", proving he will be there for her regardless of sickness or health.
In Rubicon, Murphy is in the Dead Zone with Thelonious Jaha and a few other Sky People trying to find the City of Light. They noticed an abandoned cart and go over to investigate it. A female Grounder jumps out and threatens them with a knife. Jaha tells her that they are looking for the City of Light. She tells them that her name is Emori and that she and her brother were on the way to the City of Light when they were attacked and he was killed. She offers to show them the way if they pull her cart. Murphy offers her some water and she thanks him.
On the way, Murphy asks her why she is going to the City of Light. Emori tells him she was kicked out of her clan for having a deformity and shows him her hand. He tells her that she should not cover it up. He also tells her that he killed two people, but had his reasons for doing so.
After walking for a short while, a Grounder appears on horseback and aims a rocket launcher at the group. Emori puts a knife to Murphy's throat and tells everyone to put their supplies in the cart or they will die. Jaha tries to convince her that they can work together, but Emori tells her no. She whispers something into Murphy's ear before knocking him out.
In Wanheda (Part 1), Murphy is on the shore of the island when a boat horn is heard in the distance. Thelonious Jaha tries to convince Murphy to come with him but he refuses. When the boat arrives Emori is driving it. She calls out to Murphy, he smiles and he asks her who she stole the boat from. After refusing to leave with Jaha, Murphy eventually gets on the boat.
In Wanheda (Part 2), Murphy asks Emori what she is doing there. She tells him that she and her brother were recruited by a woman who comes to them in drones. They collect technology for her and bring it to Gideon on the island. Later, while Emori and Murphy wait for her brother Otan to return with Jaha, she tries to steal the gray case from Gideon because she has other buyers. As she reaches for the case, Gideon opens his eyes and grabs her by the throat. Murphy tries to help her but Gideon's grip is too strong. Emori grabs a knife from her waistband and stabs him in the neck, killing him. She grabs the case and runs towards the boat with Murphy following behind her.
As they wait for Otan to arrive, Emori tries to open the case and tells Murphy that she will split whatever is in there with him. She kisses him on the cheek for trying to save her earlier. She is able to pry the case open and inside they find technology with the infinity symbol on it. Murphy realizes that the case houses A.L.I.E. and Jaha had brought her with them. Later, Otan shows up and Emori asks him why he's not wearing the cover for his face. He demands Murphy gives him the case and grabs his sister and holds a knife to her throat. Jaha arrives and tells Murphy to hand him the case. Murphy holds the case over the water and tells him to let Emori go first or he'll drop it. Jaha tells Otan to release Emori. Murphy throws the case into the water and boards the boat with Emori while Jaha and Otan run to retrieve the case.
In Hakeldama, Emori has now recruited Murphy into the con game she had with her brother Otan. After their latest heist, Emori expresses her desire to search for her brother, but Murphy tells her that's it's a bad idea. Later, during another con, Murphy is lying in the road as bait, while Emori hides in the trees. Three Grounder warriors from Polis appear. They begin to search Murphy and quickly realize that he is the thief they have been looking for. They question him regarding Emori's whereabouts but Murphy's tells them that he is alone. One of the warriors search his bag, while another prepares to kill him. Suddenly, the Grounder searching the bag stops the other from killing him when he finds the blue pill Jaha gave to Murphy. He tells the other warrior that the pill contains “the sacred symbol”. They arrest Murphy and take him to Polis.
In Fallen, a chained Murphy watches as Ontari undresses. She proposes for them to have sex. Murphy refuses, telling her that he can't because there's someone else: Emori. Ontari indirectly threatens his life while comparing herself to Emori. Murphy ends up giving in and it is assumed that they have sex.
In Demons, Murphy finds Emori in Polis. They reunite and head to a room, where they sleep together. Murphy then tells Emori that Ontari isn't the real Grounder Commander. Jaha later appears in Polis, and he claims to know that Ontari isn't the real Commander. He then reveals that Murphy told him this knowledge, leading to him discovering that Emori has taken the City of Light chip. Murphy is then locked up, as Jaha persuades Ontari to take the chip as well.
In Red Sky at Morning, A.L.I.E. and Jaha request Emori's help to prevent Murphy from destroying Jaha's backpack that was being used as a mobile transportation unit for A.L.I.E. Emori enters and tells Murphy that the backpack contains a nuclear fuel cell which, if destroyed, will irradiate the entire city causing Murphy to stop and work more carefully to destroy it. A.L.I.E. uses Emori to stall Murphy and prevent him from destroying the backpack until her migration is completed. Emori warns Murphy that if he destroys the City of Light then all of its residents will be gone including her causing him to stop. Pike destroys the backpack instead and Murphy runs to Emori to ensure she is okay and she tells him he is too late. Murphy then covers her face and leaves her to prevent her from following them.
In Perverse Instantiation (Part 2), Emori is part of the group under A.L.I.E's control sent to prevent Clarke from destroying the city of light. When the City of Light has been destroyed, Emori like the other residences regains her control and freedom. Emori and Murphy reunite and hug as she apologizes to him.
In God Complex, Murphy did everything he could to protect Emori from being tested on. When they were tied up, Emori seemed to accept her fate and tried to persuade Murphy to live. She begged him to "Survive, please", showing her feeling for him. When Miller went to drug her, the last thing she did was look at Murphy. Murphy repeatedly begged for Emori's life, stating that he loves her and he will kill anyone who hurts her. When she is taken and the doors close, he let out a painful yell of anguish.
Sometime during the six years after Praimfaya, Murphy and Emori broke up. For the last six months, Emori roomed with Raven instead of living with Murphy.
Murphy also broken off from the rest of Spacekru and needs watching. Emori states she'd rather choose toilet duty over him.
In "Shifting Sands", Murphy escapes from Charmaine's group and runs into his. Emori is angry yet not surprised he left Raven, though he explains she made a deal to get him released. In the car, Murphy's shock collar activated, and Emori without hesitating reached out to him, getting shocked herself. Once it stopped, she spoke to him, seemingly worried, asking if he's alright. Realizing that the group needs to go and warn Bellamy, Murphy says he has to stay [as the collar has a perimeter shock set and a tracker], and tells the other to go. As the car pulls away, Murphy is surprised that Emori has stayed with him - showing despite their current bad blood, she still cares for him him.
In "Damocles (Part 2)", Emori is willing to die with Murphy, "There's no way in Hell I can leave the man I love behind", when he is wounded and too weak to make it to the Gagarin. He tells her to leave, not wanting her to die - preparing to die alone [something he told Raven he never wanted to do "I don't want to die alone"] - showing he loves Emori more than anything. Later, on Eligius IV, Emori visits Murphy after Jackson removes the bullets.
