Isso é abordado na Novelização Oficial . Depois que David Banner acidentalmente matou sua esposa, Bruce ficou furioso, atacou seu pai e fugiu de casa, levantando o alarme com a Polícia Militar. Devido a sua condição de "ahem", ele foi incapaz de dizer à polícia em que direção sua mãe havia deixado, algo que, inadvertidamente, contribuiu para sua morte por perda de sangue.
“But she surprised me. It was as if,” and he spoke in a singsong voice, “as if she and the knife merged into one thing. You can’t imagine—” Betty was wide-eyed as he stared at his empty hand. “—the unbearable finality of it, her life, and mine, suspended at the end of my hand. . . .”
. . . and he flew at his father, who was staring stupefied at the blade, which was still dripping with the blood of his wife, Bruce’s mother, and he remembered at the last moment to bring the knife up, but the boy was upon him then, leaping, knocking the knife clear, and although the monster wasn’t yet unleashed, wasn’t yet anything approaching his full strength, the glimmer of its potential was there, and the father looked into the eyes of the son and knew fear as the boy tore at him like a wildcat, and the boy lost track of his mother, saw her stumble in shock and confusion out the front door, and then his father tried to throw him down so he could get at the knife . . . and . . .
“And in that one moment, I took everything that was dear to me . . .”
. . . he sank his teeth—like an animal, like a berserk, rabid dog—into his father’s neck, and tasted his father’s blood between his teeth, and the father howled and shrieked and the screams of the father blended and overlapped with the howling of sirens . . .
“. . . and transformed it into nothing more than a memory. . . .”
. . . as the MPs swarmed the house, and his father was dragged away and shoved into a car with whirling lights atop it, and Bruce was screaming and pointing in the direction he’d seen his mother stagger off, but no one could understand him because he wasn’t speaking, he was grunting and growling inarticulately, like an ape crying out in distress, and someone was trying to hold him steady and he struggled and yanked and shrieked and the rage seized him and his body started to bubble for a moment and someone yelled “He’s got a swelling here, it’s huge; get some ice packs, stat!” and “We need to sedate him; he’s having a seizure!”
No filme, a explosão verde na distância (e os olhos de Bruce se tornando verdes) são presumivelmente indicações de que ele começou a se afastar.
