Oh, lover, I’ll cover you.
Not sure if you know this, John of course is a very seductive lip licker which gives us 'those moments ' when we know that he is in an interesting place in his head.... but is this a john thing or a Martin thing? I've been watching out for it in other Martin roles but don't see it so are those lips licked just for Sherlock ? Wow that's a mouthful to say!! Haha
