The Doctor travels to Arthur's World to aid in his birth; the Doctor used the alias Merlin but discovered that he was the second person at the time to use the name Merlin. The other Merlin was another renegade Time Lord who had given Arthur and his kingdom advanced technology and prompted Morgaine to seek an alliance with them. This other Merlin, disguised as the Doctor, was imprisoned in the Arctic by Morgaine after she was temporarily banished to a desert by the Doctor, leaving the Doctor to set up the events that would later be experienced by his seventh incarnation.
- The Doctor mentions that he is new to this body and has trouble piloting the TARDIS.
