How do you know there've been no consequences? Good storytelling, especially in a cinematic universe, doesn't plop a consequence immediately after an action, it takes time to build up to consequences. We've had ONE movie since Civil War and that's been a breather introducing Doc Strange. We're not going to see some fallout until Spider-Man (or Iron Man 5 feat. Spider-Man if RDJ has anything to say about the script) and on top of that, the Russo Bros have already revealed that Cap's retired and has asylum in Wakanda, Bucky decided to freeze himself again in the post credits sequence of Civil War, and the Avengers have essentially broken up. I'll be shocked if Peter doesn't have a lot of issues with Tony going into Homecoming
