The various names of the Wanderer and the Doctor, the last of the Time Lords. Also, comparison of the regenerations the Wanderer and the Doctor know each other in.
The Wanderer IIII (upper left corner) knows the Doctor X. The Doctor X also knows the Wanderer V, who also knows him as the Doctor XI. :)

The Wanderer regenerates and is once again a redhead . . . the Doctor's jealous. :)
 
Also, she needs glasses (that's a first), so she steals the Doctor's. XD

The dying third Wanderer used the Chameleon Arch to turn her fourth self into a human, who, like all her previous selves, can never sit still. :)
