In an interview with Empire, Mike Colter (Luke Cage) talked about how the team will initially get along.
Daredevil, Jessica Jones, Luke Cage and Iron Fist are all pretty different people from each other and those disparate personalities won’t click at first.
As Colter jokingly notes, this is very similar to the logline for The Hangover.
In true superhero fashion, it’ll be a bumpy road before they start getting shawarma together.
