Forum:The Three Doctors not Season 6B?

Forgive me if this is obvious (or conversely, a load of gibbering nonsense), but most of my Doctor Who knowledge is from the 2005 revival and bits and bobs of the classic series. I know of Season 6B being established in TV Comic and the BBC Past Doctor Adventures and I know of the CIA being referenced in The Deadly Assassin, though I've read and watched neither.

Currently, the Second Doctor's page effectively says that two contradictory accounts say that either the CIA sent the Second Doctor to the incident with Omega, or that Goth sent him there some time after The Invasion (and implicitly, before The War Games).

Now, given that the CIA wasn't actually established nominally until The Deadly Assassin, I'm assuming that the Time Lords that summoned the Second Doctor to sort out the black hole aren't explicitly said to be them (behind the scenes comments from Holmes aside). So, is The Three Doctors said to be part of the Second Doctor's post-trial adventures in the novels (but not PROSE: Future Imperfect), or is it a (not unreasonable) assumption based on (according to the CIA page's behind the scenes section) the CIA is behind all missions assigned to the Second and possibly Third Doctor? -- Tybort (talk page) 15:31, November 10, 2012 (UTC)
