Bat!John is pissed off at Sherlock. Probably used all his food as an experiment again.
It was discussed in the ‘stream, and thought it’d be amusing if bat!John spoke no English, and so Sherlock was clueless on what all he said, and was just like “What, are you hungry? Here have a strawberry.” Except batJohn is telling him to go piss off or something. (I think it was Zoe’s idea. *lol* Best idea.)
You know what would be amazing? If Sherlock couldn’t hear him, mostly, except for the very lowest sounds. Bats have mostly ultrasonic voices, right?
What am I DOING. Oh god, I am not world-building for freaking batJohn. *puts hands over eyes*
