This is the chapter where we really hit our stride and started charming the pants off everyone, lol.

Jawn held up his hand, pointer finger extended, hovering above
Sherlock’s face…then jabbed the little detective square on the nose,
making him go cross-eyed. “BEEP!”

Sherlock’s eyes went wide and he clasped both hands over his nose.

‘Oh God, here we go,’
Mycroft thought. He strode over to the pair, fully anticipating the
moment when Sherlock would burst into tears (and he couldn’t really
blame him this time; that jab had looked hard from all the way across
the room!), when the overgrown tyke surprised both of them by dissolving
in huge, gut-busting belly laughs. “ ‘gain! ‘gain!” he chanted, moving
his hands out of the way and Jawn, grinning like the Joker in a pack of
cards, poked him again.
