Re: Which Trek author is best at retconong stuff?
IIRC the ties to TOS were kind of the point to the whole series. I believe that the creators of Vanguard said in interviews that the whole idea behind the series was to explore what was going on at the same time as TOS, and to provide new background and perspectives on what we saw in it.
Over the course of many encounters and many years, I have successfully developed a standard operating procedure for dealing with big, nasty monsters. Run away. Me and Monty Python.
