At "night" on the TARDIS, Ian Chesterton and Barbara Wright find a black board with "BARB-A-IAN" written in Susan's handwriting. Though the two assume that Susan was mocking human knowledge, she assures them that it was from before their travels, hastily erasing the writing, before telling them not to wander around the ship.
With the tour done, the Doctor goes off to bed, leaving his granddaughter to show the humans back to their rooms. Before that however, Susan, aware that her teachers will snoop around, shows them the art gallery where she's recreated several of Earth's more famous paintings and some sketches of her teachers. To Susan's relief however, far from being offended, Ian and Barbara are delighted by her drawings of them.
- This story was release in conjunction with a Humble Bundle event.
- Susan plays on the connection between Barbara's name and the word "barbarian". Takagi Mamoru was also amused by this connection. (AUDIO: The Barbarians and the Samurai)
