When John Dee escapes from the psychiatric ward in Episode 3 (“Dream a Little Dream of Me”), he makes his way to an old shipping container where the ruby is kept. Morpheus also finds the ruby, but Dee’s modifications to the jewel actually knock the Dreamlord unconscious. However, it all plays out very differently in the comics, mostly because Morpheus actually gets some help from a certain member of the Justice League: Martian Manhunter. “The Sandman” is technically part of the DC Universe, and Morpheus enlists the help of Martian Manhunter and Mister Miracle in finding the Ruby in “Sandman” #5.
After briefly rescuing Mister Miracle from a horrific nightmare about the planet Apokolips, Morpheus speaks to Martian Manhunter about the whereabouts of the Ruby – because he knows more about older artifacts the Justice League have encountered. But the green alien immediately recognizes Morpheus as “Lord L’zoril” and bows in horror, seeing the Dreamlord as a flaming black skull even more intimidating than Morpheus’ usual pale face.
Manhunter quickly explains that the ruby is in a security facility outside of Gotham City, and Morpheus immediately travels there while Manhunter and Miracle retrieve Oreos from a secret stash in the team’s kitchen. Gaiman recently discussed omitting some scenes from the comics, explaining on Tumblr, “Making Sandman for Netflix is a chance to do it again, with the economics of not existing in a shared universe in the same way.” to have to . So when we do the Joe Simon and Jack Kirby Dream Dome Sandman stuff, we do it a little differently, and we don’t need the Justice League scene to get Dream to the Ruby.
