Much like last week's episode, this two-part adventure really seems to be preparation for Maisie Williams' new and exciting character. No longer referring to herself as Ashildr, we find 'Me' in London, 800 years later than where we left her with the vikings. Being immortal, she has isolated herself from the world as losing the ones she loves has become too painful, something the Doctor can relate to. Me has taken to the life of an outlaw and has teamed up with an alien with the promise she will be taken far away from her life on earth.
Me has lost her way and no longer has the compassion and care she once had. Years of being alone have turned her into a cold hearted, bitter woman. However the Doctor and Me offer fresh and witty banter, at one stage working together to steal an amulet in a comedic scene. This raises the question: Even though the Doctor is reluctant to take Me along for the ride at this stage, will she one day be a companion? Or will she become the new Riversong, returning throughout Capaldi's time as the Doctor?
But of course, the story doesn't end here. After remembering she does have a heart, Me, (or maybe Ashildr again?) asks the Doctor to help her save the town from the manipulating alien she has befriended. In this process, Maisy uses the second of the modified Mire computer chips to foil the alien's plans and save a fellow outlaw.
More questions! Will these two become an invincible dynamic duo? Will Captain Jack return for an episode now the Doctor has suggested he will catch up with Me/Ashildr?
However the most important question from this episode is just who will Me/Ashildr become? She has vowed to watch over the Doctor's companions once he tosses them aside, but a photo of her giving the Doctor a sly smile in the distance suggests she may be much ore fun than just a reoccurring character.
