Synopsis
This issue describes a trial with accompanying flashbacks. Sometimes 1 side is just a single panel, so I have simplified the timejumps.
Matt Murdock is the prosecuting lawyer. Carol Danvers is giving evidence of how as Captain Marvel she led a superhero group to confront Bruce Banner at his 'secret' lab. (Tony Stark is called as a prosecution witness partway through, but then we unrealistiscally alternate them.)
Bruce has been 'cured' of being Hulk (since Totally Awesome Hulk #1) but in the fb CM is worried that Banner is dabbling with gamma rays and genetic manipulation. Tony Stark joins her without his Iron Man armour (mandated by CM because of his kidnapping of the Inhuman Ulysses last issue) and they lead Bruce outside where he sees a whole gathering of superhumans.
CM explains that Ulysses (who is there) gets warning visions from the future. (Stark interjects that it's only a possible future.) Each of those visions has come true but his warnings have enabled the heroes to avert the disasters. His latest vision (last issue) was of Hulk killing them all. But the super-community is split. Some follow CM wanting to intervene to stop the crises before they start. Others agree with IM that they should just prepare to deal with the crises if they happen ....
.... or at least get proof that they are going to happen. Cue Beast who has sneaked into Banner's lab while they were talking and discovered that he's been injecting himself with dead gamma cells. Both sides now accuse Bruce of trying to become the Hulk again. Despite his protests that he has actually been keeping Hulk at bay Maria Hill of SHIELD arrests him.
Banner starts to get angry. And an arrow pierces his brain, killing him.
In the fb Hawkeye gives himself up, and in the present we learn that it is Clint Barton on trial not Bruce Banner.
A different fb shows Banner coming to Barton saying that he dreams of being Hulk on a rampage. Every time he has to check the news to be sure it didn't happen, and he dreads the day when he'll find it was real. Bruce gives Clint a special arrow tip that will kill him, and tells him to use it if he ever starts to transform.
In the present Hank McCoy testifies that he found evidence that Banner created the arrow, and a video diary confirming Barton's story. And Clint says he saw Bruce's eyes turning green. Danvers claims that Barton's action saved many lives. But Stark, distraught at losing another friend due to Ulysses' predictions, says it's still murder. (And the fb repeats this disagreement, and shows other heroes taking sides.)
Later the jury reach a verdict. Tony Stark tells Mary Jane Watson he doesn't need to hear it because he knows what it will be. The AI Friday interrupts to say that she's analysed Ulysses' brain (recorded last issue) and she knows how his visions work. She shows them the future.
