The Marvel Cinematic Universe is a very big place, spanning both movies and shows that are available with a Disney+ subscription. Given just how many stories have been told, there are a number of characters and possible plot points that fans still worry about. That includes Ty Simpkins' s Harley Keener, a kid who helped Tony back in "Iron Man 3." Fans haven't forgotten that kid, but I agree with their take on his role in the greater MCU. Those of us who have spent years watching the Marvel movies in order will remember "Iron Man 3's" Harley Keener, who created a bond with Iron Man before his final mission. Ty Simpkins reprised his role at Tony's funeral, but some moviegoers thought he might have a bigger role in the future, perhaps as a new Iron Man. Discourse on Twitter tried to set those corners of the fandom straight.
