"Don't move, j-just don't move, I swear we will get you out of that!" John stuttered, the sight of his baby sister strapped to a bomb made his knees tremble. Sherlock stepped forward, trying desperately to put on a brave face and calm the situation.
"Let's not d-"
John cut him off, wringing his hands in worry.
"We don't have time for your fancy deductions Sherlock! Are you tied to it, Elsie? Have you tried wriggling out of it?"
Elsie stepped forward, hands outstretched.
"Its not-"
John once again cut her off, waving his hands wildly in despair.
"It's not coming off?! O-okay, don't move – you might set it off, uuh, umm..."
He fretted, pacing slightly to release pent up stress-energy.
Sherlock tried to cut in again, but Elsie got there first.
"John! It's not a bomb! It's a prototype recyclable desk tidy from the design department at school! Mr Hayden, our design teacher, said I could take it home because I'd finished it ahead of schedule!"
Well. That certainly wasn't what John had been expecting.
John stopped still.
"Uuh, well... That's good news! Certainly better than a bomb, I guess..."
Still suffering from the shock John focused on a spot on the ground.
Sherlock turned to John, his only friend, and gave him a 'you are such an idiot' look, muttering:
"You numpty John!"
Elsie just laughed.
