Journey Blue was a lieutenant in the Combined Galactic Resistance which fought against the Daleks.
She was once saved from a pursuing Dalek spaceship by the Twelfth Doctor when he materialised the TARDIS around her just seconds before the spaceship exploded. He took her back to the Aristotle where she saved his life, by convincing her uncle Morgan Blue that he could be useful.
Together, along with Clara Oswald, and two other soldiers named Ross and Gretchen Carlisle, the Doctor and Journey were shrunk and put inside "Rusty", a Dalek which believed the Dalek themselves should be exterminated.
When the Doctor fixed a radiation leak inside Rusty's casing, it reactivated, sent a distress signal to a nearby Dalek ship and began killing the crew of the Aristotle. Rusty was stopped by Blue, the Doctor, and Clara when they managed to restore its memory of witnessing the birth of a star. This reactivated the moral side of Rusty, and caused him to order a retreat in the other Daleks, and begin fighting them. It killed the Daleks onboard the Aristotle and left to continue his efforts against the rest of the Dalek empire.
After returning to their normal sizes, the Doctor and Clara went to leave in the TARDIS where Journey asked the Doctor if she could join him; although he thought she was kind and brave, he just wished she wasn't a soldier. (TV: Into the Dalek)
