^If that were what he were saying (and I'm not convinced it is), I'd agree with it in principle. However, the idea of a post-TMP 5-year mission is asserted in The Captain's Daughter
, which is a book I count as part of the modern continuity (since it introduced the portrayal of John Harriman that subsequent books have followed) and which I referenced in Ex Machina
. The Darkness Drops Again
also references the idea that the post-TMP mission was 5 years long, for consistency with ExM. So it's part of the modern novel continuity's take on post-TMP events, though as we've seen with Crucible
, there is room for other approaches in different continuities.
