Bo's face

For the first time, Bo's face appears in the series " End of the World " (2005), whose action takes place five billion years later in the future. He is portrayed as a creature from the "Silver Desolation" and having significant influence in the galactic community. Bo's face is funding an event that the rich are gathering to watch the destruction of the Earth as a result of the expansion of the Sun. A disaster occurs, but thanks to the intervention of Doctor Litsu Bo, most of the guests manage to survive.

In the New Earth series (2006), Bo's face is living out in the New York Hospital at 5,000,000,023. His nurse, sister Heim, tells the Doctor the legend that Bo's face is the last of his kind. The legend also says that before his death he will reveal his great secret to a wanderer who does not have a home. The Doctor later asks him about this, but Bo's face says that the great secret will wait, and he will reveal it at their third and last meeting. After that, Bo's face disappears.

The last time Bo's face appears in the episode " Cork " (2007) in 5,000,000 053 on Novaya Zemlya, almost devastated by a plague of viruses . Previously, he used his life force to isolate the inhabitants of the lower city from the virus, but now Bo's Face needs the help of the Doctor to free people from the trap, and gives his last life force to do this. Before death, as the legend says, he reveals his great secret, telling the Doctor: "You are not alone." The doctor tells Martha Jones that Bo's face was mistaken, but the existence of another time lord who survived the war of Time, the Master, is revealed later ^[1] .

In the episode " Bad Wolf ", which takes place in the year 2002, it is said that Bo's Face is the oldest creature in the Isop galaxy . In the series “The Long Game, ” which takes place a century earlier, Bo’s face speaks on television that she is pregnant.

In the series “ The Last Time Lord ”, captain Jack Harkness talks about what he will become in the future, because, although he is immortal, his body continues to age slowly. He explains that this is only a matter of his vanity, and says that, being the first member of the Time Agency (and the owner of a good appearance), he was photographed for Agency advertising posters. Given this fact and the fact that he was known in the Agency as a native of the Boshein Peninsula, Jack was nicknamed “Bo's Face” among agents. This news is shocking to the Doctor and Martha.

Screenwriter Russell T. Davis, in a commentary on the series, called the meaning of this scene “theory” regarding the origin of Face Bo, prompting executive producer Julie Gardner to urge him “stop backtracking” about the fact that the two characters are the same. Davis also said that after writing the scene, he inserted a line into the dubbing record for the Cork series, in which Bo's face calls the Doctor “an old friend.” Davis does not like to make the relationship between Jack and Beau explicit, stating "the moment she becomes very true or very false, the joke dies." He refused to publish books and comic books of spin-offs that would try to finally connect the two characters.
