This story was pretty good , from the shocking death of the doctor and Helen being wiped from existence to the strange reveal of the companion of the story being MR James, it’s a rollercoaster of a ride that feels like shada for some reason (university setting probably) with professor Snape from Harry Potter as the antagonist with its own unique big finish twist, while I did enjoy the story I kind of wish this episode focused a bit more on Helen and her grandfather, I know we got a focal Helen story in what lies inside with albies Angels but I really wanted to explore more of her family history and how that affects Helen as a character. Liv was great in this story she shows a real streak of independence here earning the standout character for this story. As we near the point where she will leave the doctor and Helen I wonder how they will all say goodbye. Overall this story is a fun time bending and shocking adventure, I’d put it at about equal to the last story (bird song) it’s fun! And a pretty decent one.
