Just as in Daredevil, the Avengers' Battle Of New York is referred to in Hells Kitchen as "The Incident", as if naming it is too shameful. This time there are far more chilling references to the human cost: they mention the fact that the city was "attacked by aliens... buildings were destroyed, people were killed". The trauma of those events is real. Daredevil showed how that was affecting the media to a certain extent and big business, but this is on a more personal scale, as revealed when Audrey Eastman is introduced as a woman seeking vengeance against supers for the death of her mother in the incident. Jessica's annoyance that she's chosen her allows her a cheeky reference to the Avengers;
"Go after the big green guy or the flag waver.
There are other unnamed references to, with one mention of "ever since those guys quote 'saved the city'" and a call to bring in "the big green dude and his crew".
