Second time. Sherlock notes with interest. Hands again.

Not the second time John has touched him, of course, but the second time Sherlock has felt... whatever this is.

And only two days since the last occurrence. Will have to–

His train of thought breaks off as the hand that before was only gripping tugs hard on his wrist. And it's as if that tug is a tether to the world, because it's only then that Sherlock realizes there's a voice ringing behind him, (John's. Distressed.) and that the rooftop he's running on ends.

High. Too high for a safe drop and no other buildings within reasonable jumping distance. Can't stop in–

But then there's another sharp yank and he's tumbling backwards with just enough time to think "Oh," before the hand on his wrist becomes arms around his chest, locking him in a vice grip to the warm body behind him.

They land hard, John's torso solid and sure beneath Sherlock's when they hit the ground. There's a breathless moment where the both of them lie gasping on the concrete roof, and then the doctor is scrambling up onto his feet, jerking Sherlock from his sprawled position as he goes.

The detective has just seconds to gather his scattered wits before John is rounding on him, spine stiff, eyes blazing. "The fucking hell were you thinking, Sherlock? Or did you just conveniently forget that this bloody shortcut ends?"

Sherlock knows he should respond to that, that he should defend himself, but he can still feel the impression of John's body beneath his, the solidity of the doctor's arms around him. He holds his hands up in a supplicating gesture and moves to step forward. His face creases with shock and pain as his ankle gives way beneath him. He looks down at said ankle accusingly, then up at John, then back to the ankle again.

The doctor sighs."Yes, alright. Come here." Even as he speaks, John moves forward, arms outstretched to support the detective. Sherlock accepts the help (and the touch) gratefully, leaning on John's good shoulder to take the weight from his traitorous ankle.

"Come on, let's get you home."
