Or did a magical fairy wave a wand over my head? [She's amused, but she shrugs it off.]

I guess it depends on what you want to believe. It's a mystical thing. One chosen in each generation type gig. You can believe that the powers get passed on or that they get activated - but either way, it happens all at once and from that point on there's just a lot more power behind everything. Speed, strength, agility, stamina. [Okay, so that was a bit flirty... but she can't just turn that off. It's her other super power.]
