I like the way you portrayed the manipulation here—all the reasons for which Alison postponed telling Peter what had happened, first, then her encounter with the Master and how scared she felt, how he had her transfixed and helpless, like a doll in his grasp. A subtle mix of simple psychological manipulation and his hypnosis powers, it was quite fascinating to see. Poor girl felt so vulnerable, even as she tried to resist him and fight back at first. His making her believe so firmly that Peter wouldn't have believed her anyway was rather chilling, and I loved his lines about the likes of them being so tiny and fragile and needing to be guided and given a purpose. If the Doctor has companions, the Master has toys, and it's really fascinating to see. Nice job :)

And aw, thanks for the mention! :D ♥
