For all it's a very deliberate spoof it never ceases to amaze me just how much New Who borrows from 'Fatal Death'. In fact given that the Doctor and Master walk away as companions at the end has got me thinking about those rumours about the Master joining the TARDIS crew.
The Master/Doctor dynamic was one of the things I enjoyed most about 'Scream of the Shalka' (another precursor that has been heavily borrowed from) and I love the idea of adding the wrinkle of a companion who's actively trying to kill the Doctor whilst working with him.
Actually, if I wasn't already writing these strips I'd have been awfully tempted to write one about a selection of Doctors and Masters sharing living space in the TARDIS. But then I'd also love to write a strip about the various incarnations of the Master having to live together much the same way as the Doctors do in the current strips. Well, I'd love to write more that is...
Time will tell. It always does.
