8. Susan
We turn our attention now towards the first companion-his granddaughter Susan. Mystery surrounds her early years as revealed in 'An Unearthly Child'. But should you dip further into 'Lungbarrow' there's a backstory which seems to conveniently add up. This posits that she was one of the last naturally conceived children born to Gallifrey before Pythia's Curse hit and rendered the Time Lords sterile. Her grandfather sends her off-world to escape. And who's her dear old gramps? None other than The Other! If we were to get the chance to see or hear the start of their familial bond-Susan having recognised the First Doctor as a regeneration of The Other in 'Lungbarrow'.- it could be a great opportunity to pair David Bradley with Carole Ann Ford. Has to be better than Richard Hurndall in 'The Five Doctors' at any rate.
