I enjoyed the second of this two-parter as it was time well spent with these “new” Silurians and with the idea that humans are–despite the Doctor’s affirmations of their qualities–in the end fundamentally fallible.
Question: whilst on the decontamination slab, the Doctor mentioned something about the “human bacteria” in his blood. Anyone else get a clearer read on this? and is there any other canon information on this (aside from the McGann assertion)?
