Dream Husbands

Dream Husbands is the slash ship between Arthur and Eames from the Inception fandom.

Canon
Dom asks where Eames is located and Arthur replies that he's in Mumbasa. Dom tracks down Eames where he tells him that Arthur keeps telling him that Inception in impossible. Eames says that Arthur is good at what he does but lacks imagination.

Back in England the group comes up with the plan for Inception. Eames comes up with the idea of convincing the target that he gave himself the idea. Arthur is impressed, and Eames takes the compliment. Late Eames think the idea that they should give the target is that his father wants him to create for himself. Dom says it might work, Arthur arguing that they need to do better than might, causing Eames to insult him for a lack of contribution. Arthur counters back that they would need more specificity in the idea. Later they need to find a way to wake up from the dream, Dom suggests a kick, prompting Ariadne to ask what a kick is. Eames kicks Arthur chair, causing him to startle and fall slightly forward. He's clearly annoyed at the action. When testing possible serums, Arthur is the test subject as Eames watches, laughing the few times that Arthur is forced to fall out of the chair and wake up.

Inside the dream the group gets into a cab where they are attacked by Fischer's mind, getting shot at. Arthur asks Eames if he's okay, and Eames replies that he's fine. The cab gets away and they hideout in an abandoned warehouse before they have to run. Arthur begins to shoot at some of the men outside, as Eames comes up to him. He tells him to dream bigger as he pulls out a much bigger gun killing most of the men at once. He heads back inside as Arthur watches him.

In the next layer or the dream, they get set to go into the next layer of the dream. Arthur helps Eames go into the next layer, as Eames tells him that the dream security is going to chase after him. Arthur tells him he's going to lead them along for awhile. Eames reminds him to be back before the kick, as Arthur tells him to go to sleep.

Fanon
Fanfiction varies for the two. Some like to explore their relationship before the events of the movie, some even speculating that they had been together during that time, before splitting up. Or that they were still together during the events of the film, but since neither is the point of view character, it wouldn't have been explored.

Those that believe that the ending wasn't a dream, like to write about them being on jobs after the events of the film and ending up together, or in some fanfiction getting back together, afterwards. Some will also explore them retiring from the Inception business, instead having a more legitimate life together post the Fischer job. Non Inception AU's are also popular. Exploring the relationship without dreams being a factor.

On AO3 the relationship is the most written for both characters, as well as the most written in the Inception tag.
