The play The Condemned confirmed that Charley was rescued by the Sixth Doctor, and she continued to travel with this incarnation until Blue Forgotten Planet.
However, in Storm Warning, Charley rebels against this existence; she styles herself as an Edwardian adventuress and runs away from home, seeking excitement.
Making an appointment to meet a young man she fancied in Singapore on New Year's Day 1931, she stows away on board the Airship R101 disguised as a male member of the crew.
[4] After a while, the web of time begins to break down as anachronisms seep into history and "anti-time" starts to infect the universe, with Charley as both the focus and the gateway.
Eventually, the Doctor discovers he is free of the anti-time infection and he and Charley manage to find their way back, accompanied by C'rizz, a native of that other universe.
She quickly changes her mind but due to a series of events involving Cybermen as well as temporal shifts and memory loss, she ultimately parts company with the Doctor.
But Mila dies saving the Doctor's life and Charley takes the opportunity to finally set the web of time straight.
She asks the Viyrans to alter the Doctor's memories so that all the adventures they shared would be remembered with Mila's name and true appearance.
The Doctor was very fond of Charley, and admitted later that she was his friend and he loved her, but what that meant for a virtually immortal Time Lord was unclear, as the relationship between the two was not a physical one.
In the bonus tracks to the Companion Chronicle Solitaire, it was revealed that Charley would get her own series picking up from the events of Blue Forgotten Planet.
