I’m guessing she’ll wolf out in SB, because seriously, how could they resist showing us that?
The real thing I’m wondering about is if she can just automatically do it, or if she’ll have to tap into it somehow, like how Regina seemed to tap into and regain her powers after contact with Emma. In Red’s case, it’s not learned magic, or a curse that was put on her, her wolf was just part of her genetic makeup. So does that mean that she’s automatically got that ability back? Maybe she wouldn’t be expecting it, after seeing how Regina’s powers originally failed, so maybe it’ll catch everyone unawares when it happens.
