Two days before the fall, John hastily signed his name onto a clipboard while trying to tell off his flatmate. It was a fruitless endeavor but he was going to try all the same. Two days after the fall, Sherlock watched from the shadows as John confessed to their landlady that he wasn’t, actually, all that mad.
A week after the fall, John took Mrs. Hudson out to lunch, and paid that month’s rent on the flat he was no longer using. Sherlock was still hiding out at Molly’s place, so he only discovered this because she’d happened to run into John on her lunch break, as he was on his way back to Harry’s.
"He’s sort of broken," she mumbled that night over the stove, cooking her dinner. She was trying to learn to cook for two now, but Sherlock still rarely ever seemed to eat. He ignored her comment and continued scanning the computer screen, writing up a list of things he needed to make his diguises.
