Whoever is running the Marvel Studios / Netflix accounts for Daredevil, Jessica Jones, Luke Cage and Iron Fist is/are really good at their job. When a fan asked who would win in a fight between Danny Rand and Matt Murdock, the twitter accounts responded very much in character. This may be a sample of how they get along in The Defenders series. Can't wait until the Punisher gets his own account.

@Daredevil @MarvelIronFist @BaireJoe Blah blah blah team blah blah justice blah blah — Jessica Jones (@JessicaJones) February 22, 2017

@MarvelIronFist Here's some free advice. If you just ignore @JessicaJones she will stop bothering you. — Daredevil (@Daredevil) February 23, 2017

And another time they talked to each other.

@JessicaJones sorry Jones, I don't just whip out my chi for anyone. — Iron Fist (@MarvelIronFist) February 19, 2017
