Heather Lake and Annabel Lake read the book together. (COMIC: The Broken Man)
Ace also read a copy of Through the Looking Glass, in the TARDIS. (PROSE: Cat's Cradle: Time's Crucible)
Behind the scenes Edit
During a segment in the comic Cat Litter which has Ace going through a series of rooms in the Doctor's TARDIS, one panel recreates a well-known illustration from the original edition of Through the Looking Glass.
The Eleventh Doctor quoted "The Walrus and the Carpenter", a poem in the novel, in The Rings of Akhaten when he explained to Merry Gejelh why she should not sacrifice herself to Akhaten.
