Where can I see the q&a?! Dis you watch it?
You had to pay / donate to watch the exclusive Q&A.
The questions he answered were interesting, but there was no absolutely new revelation or announcement... Mark seems to be having a bit of a writer’s block lately, which is why he is mostly drawn to other creative outlets / new and interesting projects. (Aren’t we all?)
He also started this unhealthy habit of falling down rabbit holes on Youtube. (Don’t we all?)
Regarding the expected question whether there are any plans for a new Sherlock series, he replied that there are none currently, but that’s also the standard answer. And, surprise surprise, a Sherlock/Dracula crossover will never happen.
There is another video of him answering general questions on Youtube, though. I posted the link to that one.
