History 101.
"The note you had wasn't actually written by Fitz, was it?" The Earth arc.
Pg 198 "I've had a while to come to terms with it. Since we were in Spain." History 101, when the Doctor finally had proof that the handwriting in the journal was Fitz's (pg 159 of that book).
Pg 200 "I've got a friend [...] that the Doctor kept waiting for over a century." The Earth arc.
Pg 201 "The TARDIS is itself made of fire. In a sense." The Burning.
Pg 223 "I have faced people who became clocks." Anachrophobia.

Pg 234 "The gun leapt from Sabbath's palm as the shot cracked round the room. He cried out and stared at his bloodied hand. [...] Without a word, the Doctor handed Sabbath a handkerchief." This moment will prove to be pivotal in forthcoming books. See Timeless (pg 8) and Sometime Never... (pg 247).
Pg 237 "That's what free will is all about." Given that the Doctor says this in the context of alternate universes, this might be a reference to Inferno.

CONTINUITY COCK-UPS
- Pg 8 "I mean this isn't 1963 after all, but I'm only eighty years adrift" It's 1893, so Fitz is actually seventy years adrift.
- Pg 94 "'The GPS only gives a ground fix,' Hartford said angrily. 'So the signal gives the same position as the plane.'" Except that, if Anji really had parachuted out of the plane, the speed with which the plane is travelling would mean that it would be distinct from her coordinates within seconds. So Hartford and his men should really be able to guess that she's still on the plane.
- Pg 251 "You wouldn't let me kill Nathaniel Ashe, and he wasn't even an innocent bystander." Is this supposed to be Nathaniel Chiltern, from Camera Obscura?
PLUGGING THE HOLES [Fan-wank theorizing of how to fix continuity cock-ups]
- Being a veteran time traveller, Fitz gets easily confused about years.
- Hartford and his crew are so upset at having been fooled that they're just not thinking straight. Just goes to prove that old adage about military intelligence being an oxymoron.
- Subtle clue that reality has been altered and Nathaniel Chiltern is its first victim.

IN SUMMARY - Robert Smith?
Time Zero is a much cleverer book than it first appears. It's not quite the brilliance we've seen elsewhere from Justin, but it's still pretty impressive, with an extremely solid story that marches forward unrelentingly and produces some really pleasing payoffs. Its status as an 'event' book does it a disservice however (it's not really and the sort of epic stuff it tries to present is laughably underambitious in a post Lawrence Miles Whoniverse). There's a really bizarre explanation for the monster from The Burning that comes right out of left field and feels as though the entire book might exist solely to throw this in. There are also a couple of clunky bits, such as the appallingly written section about the Doctor not having an umbrella at the pub. However, the reverse numbered chapters are a stroke of genius and there's some really good stuff for the regulars. Pretty impressive, all up.
