As a public service, Fair Use Law will post a short synopsis to prepare you for the onslaught of live Heroes commentary on Dan's Twitter page, starting Monday at 9 PM EST
Volume 4 opened with everyone back to normal. Even though he has a PHD, the only job Mohinder can get in America is a cab driver. Hiro has entrenched himself as Ando's Robin, even injecting GPS modules in each other's skin, which will be the big Baseball scandal of 2015 so they are ahead of the curve. Matt has either respec'd his build or decided to get "Precognition" as a power pool as he's now seeing black people and drawing the future.
Army guys start kidnapping heroes. If you are not a main cast member, you are presumed to be already kidnapped or killed. Sylar is ambushed at what he thought was his dad's house, but TK's everyone's face off and then runs off with one of the officers. He decides to start torturing him in a randomly chosen house in front of the owners and managed to pick a house that has not only a teenager with powers but also knows who his father is. The kid can shoot microwave rays and has the not-at-all-foreshadowing name of Luke, hereby becoming Luke Nukem.
Peter can only absorb one power at a time, making him manageable as a character. Peter, Matt, Hiro (who the government still thinks has powers), Mohinder (who lost his spider side effects but still can only become a cab driver), Tracy, and Claire are kidnapped. Nathan frees Claire because his illegitimate children can surely not screw everything up. Guess what? Claire screws everything up by sneaking onto the military plane and freeing Peter, who instantly steals Superstrength, then Tracy's ice powers, causing a huge hole to happen in the plane, sucking out a hero who is just an extra so we don't care if she died. During the plane's downward spiral, Claire finds her father as the co-pilot because every season needs to have Noah saying "I'm doing this to protect you" in lieu of character development.
The plane crash used the rules of "Those with their names in the opening sequence live," so no one dies. Nathan bombs the wreckage because apparently it's easier to explain a missile attack on American soil than a simple plane crash. The Main Characters meet up with Daphne and Ando, as Matt paints a picture of Daphne getting killed until she is dead. He then leads her exactly to the point where he painted, and she gets killed until she is dead, except with no blood and all gun shots hitting her coat. Matt goes insane and causes one officer to start shooting his own men. The commander of these crackshot Army guys is an insane gent by the name of the Hunter, who appears to be able to hate every powered character while also knowing everything about them. For the time being, Noah is keeping him on a short leash like this was Soft Cell's Sex Dwarf.
Tracy tries to double cross everyone, but Peter flies away at the last second leaving Tracy alone with the Army and Nathan. We close on Tracy, tied up all Guantanamo Bay, screaming "You are one of us" at Nathan while Claire, back at home, is getting text messages from someone called Rebel telling her to keep fighting.
Prediction: Rebel is obviously Caitlin, from the dark alternate future that never existed, using Alejandro's powers to somehow communicate through Micah from an undisclosed location at Ted's wife's grave site.
