With no choice but to flee, the Doctor materializes the TARDIS around himself and his companion, but finds that they're not alone inside.

Despite the Doctor's best efforts, Omega has survived from his exile in an unstable universe and has taken possession of a human form. Not only that, but the Arc of Infinity has become a more powerful weapon than ever before.
