The Battle for Time (comic story)

Opening narration box
Koltroxa has invaded the TARDIS!

Summary
Now having the power of the time vortex and control of the TARDIS, Koltroxa believes the Doctor and Donna will serve her as slaves. But the Doctor dematerialises the TARDIS back at the house in 1908. As before, they are met by two ghostly children who take them up to meet 'mother' but this time is different. Koltroxa has not arrived yet and when the future Koltroxa arrives for her children they do not recognise her. The Doctor pleads with Koltroxa to leave because the two together in the same time is causing a paradox that could rip apart the whole of the vortex. The Doctor snatches the necklace from Koltroxa to protect and save Donna and himself. The whole house including her earlier self is destroyed, thereby ending the paradox. The Doctor tells Donna not to think to much about how the same house could be destroyed in 1908 and 2108 or it could drive you mad!
