Ooooh I love the stages of this, the little snippets of their adventures as Missy realizes where she's at in her recovery and realizes the Doctor really isn't all that prepared to help her stop reveling in killing. You absolutely nailed their characters, I laughed aloud at "stop being so vanilla" and "your morality is as gray as your eyebrows". The character development you gave Missy in this was really lovely. All in all, a fantastic fic.
I never knew just how much I miss Missy until now. I wish the season finale had been in your capable hands. Looking forward to a continuation of this story. Thanks so much for sharing!
This is lovely; funny and unexpectedly moving. Thank you for writing it.
