Summary: Inclement weather makes for uneasy flatmates.

John sheltered against the alleyway wall, squeezing his shoulder and vainly wishing for a heat pack to ease the spasming muscles.

And a drink. Multiple drinks. In a warm pub, protected from the low-pressure system that had spent the last week raining and sleeting on London's criminals and detectives alike.

Also a dartboard, with a certain consulting cockhead’s face on it.

Sherlock’s boredom at being cooped up had made for an unwelcome third flatmate, John admittedly no less snappish as the falling barometer seized up his shoulder completely. By the time a murderer braved the elements and brought them out, John wasn’t even sure he wanted to follow Sherlock’s terse instruction to stand amid the persistent icy drips filtering from the eaves.

He shifted, uncomfortable. Presumably he’d know what to do when—

A man burst around the corner, Sherlock barrelling after him. Both skidded to a halt as John stepped out of cover.

“Stay where you are!” John yelled, gun aimed in unshaking hands, his shoulder faded to a background buzz.

They grinned at each other around the upraised hands of the suspect, spat forgotten.

Apparently a rise in atmospheric pressure had been all either of them needed.
