Depicted with facial hair and sunglasses, his backstory hinges on a pivotal survival: the family miraculously clings to a root branch after their car plunges off a cliff, a moment symbolizing the crushing burden of his choices. His actions stem not from malice but a shattered psyche warped by grief and a distorted quest for atonement, clinging to the irreparable fragments of his past.
