In case you still have doubts that Mofftiss won’t make Johnlock canon because of what people might think:
There is comic sans in the pilot.
Mrs Hudson’s restaurant sign was written in comic sans.
Mark Gatiss and Steven Moffat were fully willing to let this air. If the BBC hadn’t wanted them to do the more polished, landmark version of the show we have today, we would have gotten an entire show with this sign in it. Like. Six hour-long episodes a series. With this sign.
In comic sans.
