"A high-functioning sociopath should not have this feelings," Sherlock muttered to himself.
"What feelings?" John asked, having heard Sherlock's quiet grumbling.
"Love," Sherlock spat.
John was shocked. Sherlock Holmes, in love? What a silly idea. But John could not stop the flare of hope and longing wash through him.
"Who's the lucky girl?" John wondered aloud.
"It's not a girl, John, don't be stupid!"
"Oh... Who's the lucky bloke?" John braced himself to hear a name other than his own. He was almost trembling while wishing that Sherlock would say his name.
Instead of answering, Sherlock walked toward his partner, cupped the shorter man's face in his hands, and gave John a kiss. Baffled at his behavior, Sherlock quickly pulled away.
"Why did I just do that?" Sherlock asked no one in particular.
"Doesn't matter," John said, "Just please do it again."
