Man, what a loaded question! If we're talking about 'Teen Wolf' or similar lore, the Alpha's lineage is always a tangled web. In most werewolf mythos, being a werewolf is either inherited or transmitted via bite—but it's rarely straightforward. If the Alpha has another daughter, her status would depend on the rules of that universe. Some stories make lycanthropy a dominant genetic trait, while others treat it like a curse tied to specific conditions. I love how 'Wolfblood' handled this—being a werewolf was genetic, but awakening the powers required emotional triggers or lunar cycles. So yeah, she could be, but it's all about the narrative's internal logic.
Personally, I’d dive into her backstory. Was she born after the Alpha’s transformation? Did she ever get bitten? Maybe she’s a latent werewolf, unaware of her potential. Or perhaps she’s human but carries the gene, like a sleeper agent. The drama writes itself! The idea of siblings with divergent destinies—one embracing the beast, one resisting—is chef’s kiss. It reminds me of 'Hemlock Grove', where the werewolf legacy split families apart. Either way, I’m here for the angst and moonlit showdowns.
