The Doctor is chasing the Koltroxa through time ...

Summary
The Doctor takes the TARDIS to the future energy source that is feeding the Koltroxa and enabled her to escape. The Doctor and Donna find themselves back at the same house in the year 2109 where a Professor Rubenstein has built a time-flux analyser at a weak point in time and space, with a history of ghostly sightings. The machine is unstable and has been leaking time which the Koltroxa has been feeding on. Suddenly there are two Professor Rubensteins, one of them turns into the Koltroxa who leaps forward and throws the switch to the machine. The Time Vortex is exposed and time begins to merge. People from different times appear and in panic a Roman soldier strikes the crystal at the heart of the machine causing it to shatter. The Doctor snatches the necklace back from the Koltroxa which protects the Doctor, Donna and the Professor when the time fracture seals itself with the house being consumed by the vortex. Leaving the Professor to explain the house's disappearance the Doctor and Donna leave in the TARDIS only to find that Koltroxa has become part of the TARDIS
