Sometimes you just have to write it down, otherwise it will never leave your head.
For them the fallout starts when physical manifestation of failed alien invasion are almost gone. Manhattan is cleaned up and building crews can be mistaken with ones you can see every day in thriving city. Businesses are open, people do not look to the skies with fright, instead looking to their smartphones. Almost like before skies were thorn open and army led by god attacked the city.
SHIELD is back too. Debriefs are over, analysts have reported, evidence has been deposited, R&D are having a field day playing with tech gathered. Even helicarrier itself is fixed and unless someone tells, there is no sign of battle and explosion.
Starks tower is back too and shines over city rebuilding itself. There is still some works on progress, but you can easily believe the construction crews are there to improve, not to rebuild after crazy god.
People have adjusted too. Captain America most of time is away, meeting vets and lobbying for their support. It is taxing, but you have to be blind to not see how pleased Steve is when he realizes he has an influence that do not come with fist or half naked woman dancing around him.
Bruce and Tony are acting like weird couple, where the demonic seducer Anthony uses his scientific villes and strategically placed drool-worthy lab equipment to lure Banner in science debauchery. Pepper are extremely pleased with their cooperation – 99% of their achievements are either too obscure, dangerous or meant just for avengers, but remaining percent are enough for her to plan new product releases for next few years.
Thor has shaken off the guilt induced depression and now is constant fixture in Starks tower that they yet cannot get themselves to call Avengers tower. It is possible that great role in getting Thor back in merry mode is played by Jane sharing star gazing nights on one of Starks balconies.
You could say that Natasha is ok too, she spars with Steve, appreciates innovations from scientists, keeps SHIELD desire to control avengers checked while keeping avengers independent, gathers data, runs analysis and now and then manipulates Steve or Tony in assembling avengers to solve one or other problem. You have to know her better then she allows most people, to notice that Black widow is thrown out of balance.
Even Clint has passed his tests, evaluations and initial therapy meetings with SHIELD's best shrinks in flying colors. Yes, he deeply regrets everything that happened while he was under Loki control, welcome, the report about suggested changes to cover weak spots in SHIELD protocols are delivered to Hill and Fury, Thank you, yes, Coulson was a good friend of him and Clint deeply regrets his death, No, you don't have to remind Clint that what happened isn't archers fault. SHIELD shrinks agree in one voice – the mind of archer is flexible enough to deal with this and they are confident Barton can be cleared for active ops beyond ones with Avengers (where no one asked their opinion) real soon.
You had to know him better then anyone else to see that Hawkeye is on verge of breaking.
