"This feels like running away." Sherlock dropped his backpack onto the seat beside him and slumped down opposite John.
"It's playing safe." John replied with a smile. "Anyway, I have something for you."
His friend raised an elegant eyebrow.
John smirked and flicked a glance up at the overhead luggage rack. On it sat the old battered sports bag that Sammy brought back from Sherlock's home seemingly a lifetime ago.
Eagerly Sherlock lifted it down.
"You play?" Sally asked, looking over his shoulder before taking a seat across the aisle.

"Yorrick, I presume?" Greg laughed and slid into the seat opposite Sally.
"Everyone's a comedian tonight!" The younger man exclaimed, exasperated.
John chuckled.
"Maybe you should put him away for now, we don't want to attract unwanted attention."
Sherlock nodded and carefully slid his grinning friend back into the bag.
"Thank you John." He said softly.
"You're welcome." John replied "I was sure that you wouldn't want to leave them behind."
