That night the Doctor leads the travelers as they break into the library, but the librarian turns before their eyes into a fungus-like creature. The Doctor kills the creature by setting it on fire and retrieves the book. The Doctor tells Miller that Kale has also been infected by the creatures and it was him who shot at the Doctor and Benny. He has similarly infected everyone on the space station via fungal spores and the planet is now defenseless and they cannot call for help.
