Leo Jones
Leo Jones was the son of Francine Jones and Clive Jones, the brother of Tish Jones and Martha Jones, the father of Keisha Jones by his girlfriend Shonara, and the cousin of Adeola Oshodi.
When Leo Jones celebrated his twenty-first birthday with a party he didn't want because of his parents' constant bickering, the party ended in a fight when his father's girlfriend, Annalise, claimed that Martha's trip to the Moon never actually happened. Leo took off to console his dad while Tish talked to their mother.(DW: Smith and Jones)
Leo witnessed Richard Lazarus turn forty years younger and witnessed the havoc that Lazarus created when he mutated and began a feeding frenzy to power his rejuvenation. He also met the Tenth Doctor, who he could tell was loved dearly by his sister. (DW: The Lazarus Experiment)
On the day Harold Saxon took office, Leo was in Brighton with his girlfriend and daughter when the Master had his parents and sister arrested, so he avoided capture after Martha warned him to stay away and hide with friends. (DW: The Sound of Drums)
- It is unknown what happened to him during The Year That Never Was. In an unmade, deleted scene, Tom Milligan found Leo during the Master's reign. He told Martha that Leo was part of the slave force in the north and had had to change his name, as he could not risk having anything to do with her.
Once time reverted to its correct point, Leo was seen with the rest of the Jones family, but appeared to be the only one with no memory of the Toclafane invasion and the Master's reign. (DW: Last of the Time Lords)
