I'm not familiar with Dr Who so I'm not sure what you are talking about...
In the mean time, I've got a topic:
Remember way back when, when little Nanoha lay dying in the snow after being brutalized by a stealth droid? With Vita freaking out beside her?
I've got a feeling, that Nanoha had died back then. She's alive now, but that's not her. It's
Bernkastel who replaced the dead Nanoha in the current kakera, in a game played against another witch of dimensions.
Did she succeed? We don't know. But at least we know, that Bern is there.
Because Subaru and Teana saw something, in Nanoha's eyes.
And the way she told them to cool their heads.
