Doctor: Regeneration does nothing to memory. Except that time with the hospital in my 8th regeneration, but everything came back quite quickly. I remember nearly every moment of my life, even the moment before I was born while I was still in the loom. You think I would forget something that important? Just hit the blue squanky button and give the whirly tube a kick. Should fix everything right up and send you both on your way to whatever multiverse you’re from.
