Tony returns to Earth as he does in the movie and has it out with Steve. He remains at the facility as he recovers physically and exhausts every resource trying to undo the snap.
After a year of work and increasing troubles with his sobriety, Tony moves into Pepper and Rhodey’s country home for support, no hope left. The two are a couple and have, by this time, welcomed a little girl named Morgan into their family. Rhodey is frequently gone due to missions, but Tony proves to be an excellent uncle.
When approached about Scott Lang’s idea, Tony isn’t reluctant because he’s afraid of losing what he’s found. Tony is reluctant because he doesn’t want to dare hope, just to lose it all over again.
While Bruce is now able to work cohesively with the Hulk, he is not permanently in that form, and the two retain their separate personalities.
Thor rules justly over New Asgard, despite being depressed and bordering alcoholic. He’s not the misaimed comic relief he became during the movie.
Upon meeting Howard, Tony offers more of a warning regarding how to treat your children.
When Howard says, “Let me tell you. That kid's not even here yet and, there's nothing I wouldn't do for him,” Tony responds with. “You remember that feeling. Intentions are great, but they’re nothing if you don’t follow through.”
The Starker reunion goes precisely as it does in the movies, if not with a little more tears from Tony and a fierce kiss to follow the hug.
Tony still swipes the gauntlet and performs the final snap. While it would be otherwise fatal, he receives a small blood transfusion from Steve. The dose isn’t enough to turn Tony into a super soldier, but it does heal his wounds faster, albeit painfully. He has scarring along the arm he used, tapering off towards the bottom part of his neck and down along his side.
Peter has his heart breaking goodbye with Tony before the savior passes out, and Steve runs forward to assist.
After Steve returned the stones to the moment they were taken from, Natasha was returned from the soul stone. It’s unknown whether this was due to her heroic sacrifice, or if the stone was rewarding their use of the stone for good and nothing else.
Steve chooses to return, rather than remain with Peggy.
