Those purple people in panel 1? We all see them without seeing them, the silent swarm of humanity you avoid as you move through the day taking care of your important tasks. No time to talk or interact, so keep moving. Still, if you were to walk up to one and suggested getting a cup of coffee to pass the time, you might get pepper-sprayed or arrested by the cops. Yes, they are real people just like you or me, but it’s safer to dismiss them out of hand. And you move on.

Rivera adds some humanity to these purple people from time to time: That guy checking his watch as if he realizes he forgot what time zone he was in and arrived an hour too late. The gal enjoying a chat with her beau, while peeking at the angry dude behind her. The angry dude leaving the city with a carry-on full of misery, because his girlfriend broke up with him; yet not realizing she is currently talking with that gal on the phone. Then there is the guy sitting next to Mark, miffed that he can only hear Mark’s side of the conversation.

Finally, there are the shadow people, mere darkened silhouettes that barely pass as human forms, devoid of any differentiation. They are hardly more than extensions of seats, sidewalks, and windows as we pass them by with little more than a moment’s notice. Oh, they say there are a million stories in the Naked City, but we wound up in Mark’s.
