Once he's properly introduced, the show delves into Luke Cage's origins and powers. The bar fight scene established that he has unbreakable skin and super-strength, just as he does in the comics, and he alludes to the fact that he was "created" by an experiment. In the comics, the experiments that turned him super were designed to clone Captain America's super soldier serum - an idea the show explores in another episode (more of which later) - which was based on historical experiments like the despicable Tuskegee experiments. There's also something in the fact that Jessica Jones assumes he knows how to get drugs, since that's the crime that sees him erroneously locked up in the early days of his first comic book run. There's also an outing for Cage's iconic (but silly) catchphrase "Sweet Christmas" after he and Jessica get it on.
