Sherlock watched John and Mary dance at their wedding, surrounded by happiness. He stood alone, feeling a pang of loneliness. Molly, Greg, and Mrs. Hudson, his closest friends, were all dancing, lost in the joy of the moment. He longed to be part of their celebration but felt like an outsider. Just as he thought he couldn't bear the isolation, someone gently held his arm from behind. It made him smile slightly.

Sherlock: "You're late to the wedding!"
