The BBC has released new images from this week's episode of Doctor Who, titled "Face the Raven."
In "Face the Raven," The Doctor and Clara, with their old friend Rigsy, find themselves in a magical alien world, hidden on a street in the heart of London. Sheltered within are some of the most fearsome creatures of the universe, and Ashildr! With a death sentence hanging over their heads, not all of the intruders will get out alive.
Will this be the Clara Oswald's last episode as The Doctor's companion?
Doctor Who airs Saturdays at 9 p.m. ET on BBC America.
