OMG IT TURNS OUT
IN ONE UNIVERSE
SHERLOCK’S MUM SMOKED WHILE SHE WAS PREGNANT.
AND HE GREW UP SHORT.
AND ANGRY.
AND BECAME MORIARTY.
AND THEN HE TRAVELED THROUGH UNIVERSES.
TERRORIZING SHERLOCKS SO HE COULD COLLECT JOHNS.
And he calls his first John ‘Sebastian’ so he can keep him straight from all the others!
