Marvel's The Defenders: 23 Easter Eggs You Probably Missed

21. 613

This one might well have passed you by, but the bus that Luke Cage gets back from prison to Harlem is revealed to be number 613 (which you'd have to have pretty sharp eyes to spot unless you were really looking).

It's an interesting number for Cage, as in the Marvel universe, Earth 613 is the reality in which Luke Cage became the Power Fist after a series of events kicked off by Steve Rogers' assassination. He went by the combined name Power Man and Iron Fist - which itself is later referenced by Danny Rand when they meet.

As Cage travels, he spots Pops' Barber Shop, now rebuilt while he was inside. It's enough to inspire a wistful glance.
