It's been well documented as of late that Sony has been working on a deal with Marvel Studios that would bring Spider-Man back to the Marvel Cinematic Universe. His first appearance could be a cameo in "Captain America: Civil War." So, it was assumed Marvel Studios might want to have Spidey make appearances in the third and fourth "Avengers" films as well, but now there appears to be confirmation of this.

Val Broeksmit of Bikini Robot Army has been airing heaps of Sony's dirty laundry on Twitter this past week, and he stumbled upon a rather telling email exchange between Andrew Gumpert, the president of worldwide business affairs and operations for Columbia Pictures, and Sony Entertainment Co-Chairman Amy Pascal.

In these emails, Gumpert told Pascal, if the deal goes through and Marvel gains control of Spider-Man, that they don't want Spidey's next solo film to be a continuation of the "Captain America: Civil War" plot just because he would be making a cameo in it. But, Spidey's new universe would "exist in a world where that story has happened" and "superheroes are now divided into two groups."

Gumpert also shared details about Spider-Man's planned Captain America 3 cameo. Tony Stark/Iron Man (Robert Downey Jr.) would recruit Spider-Man and give him a suit. He would also meet Black Widow (Scarlett Johansson) and of course, Captain America (Chris Evans). Furthermore, Marvel would like to start the next Spider-Man solo film with Peter Parker back in high school, living with his Aunt May at their home in Queens, N.Y.

Beyond that, Marvel desires the Wall-Crawler to appear in the "Avengers: Infinity War" movies that will be released May 4, 2018 and May 3, 2019. In order to make that happen, Marvel wants Sony to guarantee that a second, standalone "Spider-Man" film would be released in 2019. Marvel wants that reassurance because they don't want there to be a long delay between his solo films.

Gumpert seems to be in favor of Marvel's plan and believes it will benefit Sony more than Marvel. It also appears that Pascal would rather wait on the solo "Spider-Man" films until after the third and fourth "Avengers" flicks are released.
