We haven’t seen him before inEndgame, but … should Marvel fans recognize him?

The answer is yes.

As we know fromSpider-Man: Homecoming, Stark has a soft spot for young mechanics like himself.

Why did Harley merit a cameo inEndgame, as a mourner at Tony Stark’s funeral?

Directors Joe and Anthony Russo explain:

“Clearly Tony had an effect on him,” says Joe.

Anthony asked, “Did you know who it was when you saw him?”

And EW had to confessno.

“By the way, nobody does!”

“It’s hard because he grew up since that movie!”

It’s a fun Easter egg."

It also serves a deeper narrative purpose.

Harley is the everyman to Iron Man.

Harley stands for the broader world the heroes have been fighting to save all this time.
