Regarding the Doctor and Leonardo, don't they interact in City of Death?
Nope and that was the second time the fourth Doctor failed to meet him, but he did leave him a note telling him to paint over the writing anyway.
The greatest science fiction series of all time is
Doctor Who! And I'll take you all on, one-by-one
or all in a bunch to back it up!"
