The story opens with Rhodey and Captain Marvel kissing. They are dating again, because War Machine's death has to be emotional for any of this to make sense (It still doesn't). The Inhuman Ulysses then shows up. Through painful exposition we are told he can see the future. Ulysses sees Thanos visiting Earth. Knowing he can see the future, Captain Marvel arranges for just a few heroes to fight the Mad Titan, because it's not like he's ever defeated the entirety of the Marvel Universe before.
In an awkward cut to the middle of nowhere, Thanos appears with three Liefeldian guns. The five or six heroes ambush, and, I kid you not, Captain Marvel declares, "Thanos, you are under arrest!" As you know, Captain Marvel is a stickler for the American judicial system when the entirety of the galaxy is regularly threatened by an estraterrestrial nihilistic pyschopath.
The heroes fight and one stray missile from War Machine hits She Hulk. ONE! She-Hulk's last words? "Son of a-" Yep. She-Hulk goes down making Red Foreman proud. OK, she's not quite dead yet, but close enough to trust know the rumors are fairly accurate. It's the perfect sequel to "not like this." In shock that he may have killed She-Hulk, War Machine stands, mouth agape. Thanos then runs a hand through the armor, something that he is apparently capable of but has never done before.
