The following contains spoilers for She-Hulk: Attorney at Law Season 1, Episode 1, "A Normal Amount of Rage," now streaming on Disney+.
The first episode of She-Hulk: Attorney at Law, "A Normal Amount of Rage," introduced the Marvel Cinematic Universe's newest hero. While on a road trip, Jennifer Walters and her cousin, Bruce Banner are attacked by a spaceship and crash their car. They both survive and Jen pulls Bruce from the wreckage -- but in the process Bruce's radioactive blood contaminates her, giving Jen the power to turn into a super-strong jade giant like her cousin.
Bruce takes Jen to his secret laboratory in Mexico, where he tests her abilities and teaches her how to control her gamma-powered rage. However, it's soon revealed that unlike Bruce, Jen doesn't develop a violent alter-ego to go with her abilities. Not only that, but she's surprisingly adept at using her powers, already well-versed in controlling her anger. Jen has no desire to join her cousin in the superhero business. These divides eventually morph into an all-out brawl between the two Hulks, but more than that, they shed some light on Bruce's situation and sets up future stories for the strongest Avenger.
In "A Normal Amount of Rage," Bruce explains that he spent 15 years working to balance his two personalities, culminating in the "Smart Hulk" persona that matches his intelligence with the Hulk's strength. The fact that Jen doesn't need to go through all that work to exercise the same control of her powers as Bruce clearly gets under his skin and makes him question something that clearly never occurred to him: is his split personality a side effect of his powers or was it lurking in his psyche before?
That question is prime fodder for future Hulk stories in the MCU. In the comics, Bruce's anger is explicitly linked to the trauma of growing up with his abusive father. While this aspect was a cornerstone of the much-maligned Hulk in 2003, it's never been touched on or even hinted at in the MCU, which has focused more on Bruce as he relates to other superheroes than his own past. He has always approached his alternate personality cerebrally, trying to manage it through his scientific know-how, but it might be a problem that requires a more emotionally-driven answer.
Of course, She-Hulk doesn't ignore the more fantastical aspects of its characters' stories. Bruce is able to recognize the spaceship that attacked him and Jen as coming from Sakaar, the planet where the Hulk spent two years as a gladiatorial champion and was eventually found by his fellow Avenger Thor in Thor: Ragnarok. Clearly Bruce has unfinished business with the planet, with some fans theorizing that Marvel is setting up the introduction of Skaar, the Hulk's illegitimate son who inherited his tremendous strength and lust for battle.
Whatever the future holds for the Jade Giant, it likely won't be explored in She-Hulk, since the show is about Jen's journey and not Bruce's. But the series premiere proves Marvel has more stories to tell with the Hulk. Whether these plot threads take audiences into his past or his future, there's still more to come from the strongest one there is.
