Delta Cita is an important figure in the Doctor's past: his Gallifreyan wife. To the Doctor's knowledge, Cita had died many years before the Last Great Time War. In reality, the ancient, but seemingly young woman lives among the Human race, hiding in plain sight. Fate steps into the equation, bringing Cita, the Doctor, and their childhood friend, the Master, back together in order to save millions of lives. Cita is faced with impossible choices and has to find a solution to the problem she has created. Except she sees no way out of the storm approaching them.

The Doctor was in love once. A woman he could spend the rest of his life with. Another Time lord. He had never loved anyone as much as he loved her. But...one day, the two were separated. They searched and searched, but never found each other. Time Lord Katherine Green, decided that she would continue her travels. Obviously not to other planets or times, due to lack of transportation, but around to other places on modern day earth. While investigating a suspicious High School, she runs into the last two people she thought she'd ever see. The Doctor, and Sarah Jane Smith!
