After the crawling credits finish, the Marvel logo appears and an audio teaser plays. It sounds a bit like clanking? Really, it just seems like a way to show fans the Marvel Cinematic Universe will return.  > It could be metal on metal, someone blacksmithing, someone just banging something, or maybe just an accident we all hear now. (I thought it sounded a bit like a bell but I also really had to pee.)
