In addition to introducing a new heroine to the MCU, the debut of She-Hulk helped clarify some of the gaps in Bruce Banner's 

(Mark Ruffalo) life. After all, after his defeat against Thanos (Josh Brolin), the Marvel films never even showed how the physicist 

managed to reconcile his two identities and create the Smart Hulk, first introduced in Avengers: Ultimatum, nor eventually regain his physical form fully 

in Shang-Chi and the Legend of the Ten Rings. They only gave brief explanations to situate the viewer and move forward with the plot for once.

Truth be told: She-Hulk didn't reveal such moments in full either, but offered more information about the complicated

process the hero went through, such as the fact that he was joined by Tony Stark(Robert Downey Jr) for part of it.

During the car ride with his cousin Jen Walters (Tatiana Maslany), Bruce first explains that he can return to human form and even 

recover some of the damage he sustained to his arm with the Infinity Gauntlet thanks to a bracelet he developed himself - and which, by the way, he 

was already wearing when discussing the Ten Rings with Shang-Chi (Simu Liu), Wong (Benedict Wong) 

and company. Unfortunately, the device is damaged in the car accident, so he reverts back to being the Clever Hulk.

But how the hell did he first arrive in that form? After Jen's transformation, Bruce takes her to his lab in Mexico, a gift - or, as he

calls it, "loan - from Iron Man. "This is where I stayed during the Blip, fixing myself and integrating the Hulk and 

Banner identities," he explains. "Tony built it for me a few years ago. He joked that one day he was going to show up here and take the house back."
