In 2008, the fourth season of the "Doctor Who" was focused on the adventures of the Lord of Time in the performance of David Tennant and his companions of Donna Noble, who played Catherine Tate. However, in the finals of the season, consisting of two parts, the audience was waiting for a new meeting with many former companions of the Doctor, who returned to help him save the universe from Dollur and distant.
Rose Tyler (Billy Piper) was one of those who joined the lord of time, but in the end she still had to return to the parallel universe. True, she went there not alone, because according to the plot, the doctor was cloned, and as a result, half the lord of time appeared on the world, half a man.
In order for their journey to pass safely, the real doctor gave a rose part of Tardis. This scene was eventually carved, but it can be found in additional materials to the fourth season. A few days ago, during the broadcast of the series, actors and participants in the film crew had the opportunity to share the appear details of the show, and the Tennant admitted that the scene in which Rosa receives part of the Tardis could pour into the whole spin-off.
Of course, it is unlikely that at that time there were pictures of an additional show, because the actor and so was very busy. On the other hand, David has already been filmed in Spin-off "Doctor Who" - Torchwide and the "Adventures of Sarah Jane". So, if the show about a rose was given green light, the Tennant would most likely be able to somehow compare the graphics of filming.
By the way, just a month after Piper initially left the show at the end of the second season, the Russell T. Davis Showranner told the journal "Doctor Who" about the desire to give Rosa's own series, which was supposed to call "Rosa Tyler: Earth Protection". True, Davis himself refused his idea, deciding that she would not master another large-scale show.
Of course, now that fans know that they could get another show of the Universe "Doctor Who", they hope that the Showranners will return to this idea and the history of the doctor's clone and roses will be continued.
