I thought she had been changed for good
Seems that something went wrong with Davros' 'integration' process. There must be greater forces at work here!
I wonder how much she actually remembers
It seems to me that the envelopment process (gel) combined with the electro connections (wrists feet etc) must have had some degree of control over our intrepid female here. As to the actual degree of control, which Davros would be clear about, I'm in the darkness as much as you!!! She is disorientated though, and is surprised about this considering WHO and WHAT she really is!?! But she enjoys learning about human-kind all the time!!!
