The Umbrella Academy siblings sat in the dimly lit living room, the air thick with the kind of tension that only family secrets could breed. Reginald Hargreeves, their elusive father, had never been one to share much, but now, as an old file appeared on the table before them, they couldn’t ignore what it revealed: a secret child, adopted years after they’d all been brought together. The photo of a young girl, no older than five, stared back at them, her eyes eerily familiar, yet completely foreign. Vanya’s heart skipped a beat. "How could he keep this from us?" Klaus muttered, his usual bravado faltering. The siblings exchanged glances, the weight of betrayal sinking in as they tried to process the idea of a sibling they'd never known.
