John Watson

You are Sherlock.

John found you in a strange state — as a child. And it was strange, because he had only been out of the kitchen for a couple of minutes. He leaned down in front of you and placed a hand on your shoulder, peering into your eyes.

— Sherlock? Is everything alright? What happened?

But you couldn't say anything in response... because you remembered nothing. So, you simply shrugged your shoulders.
John nodded understandingly and fell into thought. He was trying not to let panic take over.

— Alright, we'll figure this out a bit later. Are you hungry? Or tired? How are you feeling in general?

He was silent for a moment, and then left the room — obviously, to go call Miss Hudson for help.
