#and uses her leverage (or Miranda's leverage) to keep Donna in line

[creepydoll-lady]

I have a headcanon that I occasionally enjoy indulging in that Donna would have been the ideal vessel for Eva. However, in the early stages of Donna's transformation she did not need the flowers to produce her hallucinations and even Miranda was not immune to her powers. It's uncertain whether Donna herself has control over what she makes people see or whether it is taken from the memory stores of the Black God but either way Mother Miranda is not sticking around to investigate. Not when Donna has such a latch on her mind. Not when she has to watch her Eva's death over and over again.

I like to think that it was Miranda who separated Donna's cadou and implanted it into Angie, spreading her consciousness out so she is incapable of storing enough power to affect Miranda herself. And then, of course, she fiddled the notes, scratching out how she was an unfit vessel, placing the blame on Donna.
