10 MORE Unanswered Mysteries From Doctor Who
4. Where Is Romana?
Another missing face from the revival of Doctor Who is his one-time assistant and fellow Time Lady, Romanadvoratrelundar, or just Romana for short. She travelled with the Fourth Doctor and was presumed killed in the Time War, though this is also far from certain as well. In fact, it is increasingly likely that she, along with many other Time Lords, escaped that last terrible day.
Although the Master has once again destroyed Gallifrey, it would be a stretch to say he managed to wipe out the Time Lords again. Where then is the likes of Romana? Easily as capable as the Doctor in their adventures, she would be more than able to survive the storm of the War and see the machinations of the Master, even if the rest of the High Gallifreyans could not.
Though she elected to remain in E-Space, where she and the Doctor first encountered Adric, the laws of parallel universes are somewhat fluid in this show. In the audio adventures, she ends up as Lady President of Gallifrey, so another encounter with the Doctor certainly seems to be on the cards!
