G'iah, who was first introduced in the 2019 blockbuster Captain Marvel, is the estranged daughter of Fury's longtime ally, Talos (Ben Mendelsohn). The show implies she left her father's faction and went off on her own — but why?
If you recall the ending of Captain Marvel, the titular superhero — alongside Fury and Talos — promised to find the Skrulls a new homeworld; decades later, they still haven't delivered on their word. As a result, G'iah lost faith in her father and joined Gravik's (Kingsley Ben-Adir) faction of Skrulls.
She aids the Skrulls in executing a covert invasion of Earth, but upon learning of her mother's demise (possibly at the hands of Gravik), G'iah grows suspicious of the ruthless leader and secretly helps Talos — or so it seems. She reveals the rebels' plan to her father, but Fury, Talos, and Maria Hill (Cobie Smulders) learn that G'iah double-crossed them.
What comes next is total devastation, and we're not sure if Talos can ever fulfill his late wife's wishes: "Find G'iah and reconcile." This was G'iah's one chance to save herself, and she blew it — literally and figuratively.
