After Jessica and Luke have sex he says, "Sweet Christmas!" That is Luke Cage's catchphrase in the comic books.
The radio in the store mentions Daredevil and other heroes.
Luke Cage references the Hulk and Avengers when talking about "super-powered people". Trish also references the events of The Avengers (2012) during her interview with Hope, when she mentioned that the city was attacked by Aliens.
When Jessica goes into the convenience store to buy whiskey a guy on the radio is heard saying, "have ever heard of a more made-up name than Kilgrave?". This a little inside joke because although in the TV show Kilgrave is an alias made up for Kevin Thompson, in the comics Zebadiah Killgrave is the character's real given name and his alias is the Purple Man.
When Trish defends herself against an estranged autograph seeker; the fan says that he "misses the red hair". This harkens to not only Trish's earlier alias of Patsy Walker but also Patsy Walkers superhero alter ego of Hellcat.
