Sherlock was terrified. Not for his own safety. Not because his life was at risk. But because John was in danger. He knew his sister was a psychopath. But he never expected her to chain John to the bottom of a Well and start filling it with water to try and drown him.

Sherlock tried talking her out of it but when that didn’t work, he took it upon himself to climb down the well himself. As soon as his legs were submerged in the water, a chill instantly was sent through his body. The water was freezing and it was night out. If he didn’t drown first, the cold would certainly kill John alone in just a matter of time.

Sherlock has alerted the authorities before, but all he could do now was wait. Sherlock noticed the water was already up to John’s chest and John looked exhausted, probably from him attempting to get away. Sherlock quickly moved closer.

He didn’t care about personal space anymore. His main priority was saving his friend’s life. Sherlock slipped an arm under John’s wrapping it around him. He then braved himself against the well wall, holding John up so his head didn’t get submerged with water. Sherlock’s eyes were wide and it was clear he was scared, but he was trying to cover it up as best as he could.

“Hang on John. Lestrade will be here soon, we’re going to get you out of here.” Sherlock murmured.
