Synopsis
The Young Avengers (Hulkling, Kate Bishop, Patriot, Stature, Tommy Shepherd, Vision and Wiccan) and the New Avengers (Captain America, Iron Man, Luke Cage, Sentry, Spider-Man, Spider-Woman and Wolverine) are holding off Kree and Skrull troops. Both sets of aliens want to take Hulkling, who is the son of Skrull Princess Anelle and Kree Captain Marvel. Patriot was injured last issue taking a blast intended for Captain America.
Cap sends Sentry to take Patriot to hospital, while the rest of the 2 groups deal with the attackers. But then a Kree and a Skrull battleship appear above them. Cap calls to Sentry's acute hearing for help, but he won't return from his mission before the end of the battle.
Cap tries to get the YA to leave. But Hulkling points out that the aliens will follow him. And the rest of the YA won't leave without him. So the assembled heroes fight a new horde of alien soldiers.
Wolverine assures Tommy it's OK to 'kill' Skrulls, as they heal eventually like he does. This encourages Tommy to demonstrate his ability beyond super-speed - he can speed-up molecular motions causing things, or Skrulls, to explode.
Wiccan takes time out to tell Cap that he and Tommy are twins, and may be Scarlet Witch's long-lost sons (as claimed by Super-Skrull last issue).
The new Vision also tells Iron Man that he's chosen to join the YA.
Hulkling is captured by a group of Kree, and a bunch of Skrulls attempt to shoot them down. They'd rather see him dead than in enemy hands. Super-Skrull (injured in #10) intervenes to save their rightful emperor.
Super-Skrull advises Hulkling that the only way to get the alien war off-Earth is to go with the Skrulls to take his rightful place as emperor. But Hulkling hatches a plan.
Skip to a ceasefire. Hulkling has surrendered, and both alien sides have come to an agreement. He will spend half an Earth-year with each alien race, and at the end of that time he will decide who he wants to be with. Meanwhile he will be allowed regularly-scheduled visits to Earth.
After the aliens have gone, leaving Super-Skrull behind, SS reveals himself to be Hulkling. The real SS has gone in his place. Wolverine could tell. And the YA knew by Super-Skrull's formal speech patterns.
The YA and Cap rush to the hospital, where Jessica Jones is waiting. Cap intends to give Patriot a blood transfusion. But Eli's grandfather Isaiah got there 1st.
Cap tries once again to dissuade the YA from super-heroics. But once again they refuse to back down.
Later the YA are repairing the statues of dead Avengers in the grounds of Avengers Mansion, still in a bad state since Avengers Disassembled. Cassie Lang laments that there is no statue for her father Ant-Man, who died in Disassembled. Wiccan magics one up for her.
Patriot joins them with the broken statue of Mockingbird. Now he really does have his grandfather's Super-Soldier powers. Actually obtained by blood transfusion, as he had falsely claimed from the beginning.
Jessica Jones is there too. She gives Kate Bishop the bow and arrows belonging to the dead Hawkeye (another casualty of Disassembled). She also says that Kate can use the name Hawkeye too.
Hulkling scatters the ashes of his dead Skrull foster mother (killed in #8).
Wiccan tries to persuade the others that their next task should be finding his mother Scarlet Witch. Stature isn't in favour because Wanda killed her father in Disassembled.
But the discussion is interrupted by the arrival of Tommy, in a costume as Speed. he leads them off to fight Zodiac, who are attacking the UN building.
