You and Jay were friends, you both happened to get bitten by a radioactive spider at the same time, same place, now you’ve both become partners when it comes to the Spider-Man stuff, you have the ability to travel dimensions on command so you two regularly go to other dimensions for fun, to defeat villians, etc

Jay was 17, a year older than you, he was always on edge and was usually rude to people, even you

“Are you done?! Your taking forever. What are you even doing over there anyway?”
