Uploaded in A.I. form or alive and back on Earth, it doesn't really matter because in the year 2032 depicted in Amazon Prime Video original series Upload, everyone can interact with one another. And indeed, those who have passed on remain "alive" thanks to uploaded consciousnesses and replicated body forms.

Because it's possible for live people and uploads to communicate with one another, including "in person," some of the best duos on the show are actually between these two very different types of entities. However, in other cases, the uploads have become close to one another as well.

Ingrid And Nathan

Ingrid and Nathan are clearly not a good couple, though one of the things fans didn't love about Upload was the early treatment of Ingrid. Nonetheless, it was obvious that right before he died, Nathan was not planning on staying with her long-term. While he wasn't in love with her, their intense physical attraction and her devotion to him made her hard to resist.

Nonetheless, seeing them interact is always fun on the show. Whether it's Ingrid declaring her love for Nathan and how she wants to be with him forever, Nathan grimacing at the thought, or the two sharing a genuinely tender moment together, fans love the two of them together.

Nora And Ivan

Nora and Ivan were simply co-workers who became further united when she discovered that he was secretly a Lud. While they are seemingly only connected for a common purpose, their conversations are always hilarious.

When Ivan thinks Nora is interested in him, for example, he shuts her down by noting that he only dates women who are below him intellectually. Meanwhile, when she joins him in his apartment as they plot their plan, she quickly kicks him out of his own bedroom, in funny fashion.

David Choak And Prefera

It's tough not to rank David and Prefera as one of the best duos since Prefera is an A.I. that was specifically created to be the perfect partner for him. Not only is she made in the likeness of his ex-wife from the real world, but she was also created to know exactly what he wants at all times.

She can speak for him when he wants to order a meal, let others know what he's thinking, and will satisfy him in any way necessary. She's the perfect partner for a most imperfect man.

A.I. Guy And A.I. Guy

There are a lot of things that don't make sense about Lakeview on Upload, but A.I Guy is not one of them. Aside from the fact that A.I. Guy is always accommodating and jovial, just like a virtual assistant might be, he can also replicate himself at the drop of the hat when his two hands aren't enough to serve the community.

In some cases, he works together with his clones, like when they were serving at Ingrid's fancy dinner party. Seeing him interact with himself as well as others, each A.I. Guy being identical to the next, is always entertaining. A.I. Guy might not be the most intelligent character on Upload, but he gets the job, rather multiple jobs, done.

Luke And Mildred

Luke and Mildred are about as odd a couple as they come. While Mildred is technically an elderly woman, since she opted to upload as her younger self after she died, she is not only young and beautiful but also in black and white.

Luke, meanwhile, is a young Vet who immediately took a liking to the openly sexual and flirtatious woman. Despite how annoyed he gets at her ongoing stream of stories (she did, after all, live a full life), he enjoys her intimate company and puts up with it. Mildred, meanwhile, is happy with a casual relationship, not afraid to flirt with other men as well.

Aleesha And Lucy

Aleesha and Lucy didn't have much of a bond in the first season, with Aleesha and Nora doing whatever they could to avoid the annoying and strict boss Lucy. But in season 2, Lucy seemed to have taken a liking to Aleesha. After taking on more responsibility due to Nora's absence, Aleesha complained to Lucy. Instead of getting reprimanded, she got promoted.

Lucy then continued to shower Aleesha with accolades and promises – as long as she stuck with Horizon. It appears Lucy likely has ulterior motives. But for the time being, their burgeoning female friendship is adorable.

Nora And Aleesha

Nora and Aleesha – the best character on Upload - have a strong bond in the real world, working for years side by side. They understand one another since they do the same job as angels and vent to one another when a client is driving them crazy. When Nora first started having feelings for Nathan, she confided in Aleesha.

When Nora returned from her secret time off to visit the Luds and found out Aleesha had been promoted, she wasn't jealous but supported her friend. Meanwhile, when Nora got another job in a different department, Aleesha was also happy for her. They are true best friends.

Nora And Nathan

Nora and Nathan's relationship started out as the usual angel and Lakeview resident business relationship, but Nora started noticing things that suggested Nathan wasn't who she expected him to be, which was an arrogant, egotistical wealthy young man from Los Angeles.

Even beyond the romantic connection, Nora and Nathan have a wonderful friendship where they look out for one another. There's a mutual love and respect between them that transcends the fact that Nathan isn't technically alive anymore. There are as many reasons fans love the Nora and Nathan romance on Upload.

Nathan And Luke

Nathan and Luke were fast friends, mostly because Luke wouldn't let Nathan have it any other way. Uploaded to Lakeview despite not having the same financial status as others, Luke was able to get in due to his status as a Vet. Excited to have the use of his legs back, but also still working through the trauma of war, he needed an ally in his corner. And Nathan popped up at the perfect time.

While Nathan at first tried to brush Luke off, he soon realized Luke was a good guy and a genuine person in whom he could confide. It's safe to say the two had become best friends at Lakeview.

Nathan And Nevaeh

Nathan and Nevaeh have the sweetest relationship on the show. Any time he is shown with her, whether it was in scenes prior to his death or ones after, such as the Family Day events held at Lakeview, they got along so well. He is the self-described "fun uncle."

It's clear Nevaeh looks up to her uncle and was devastated when he died. She brings out the best in him and he listens to her advice while he helps keep her spirits up despite the circumstances of their visits.
