"Goodbye, Molly," Sherlock gave her a sad smile and walked out of the door.

"Sherlock, wait."

He turned back as she pulled him into a tight hug.

"Be safe," she whispered into his shoulder.

"Hey, you know me, I'm virtually indestructible."

Molly watched from her window as Sherlock got into the cab and drove off into the unknown world of Moriarty's web.

Sherlock watched from the cab window as Molly's flat sunk further into the distance. He wished he could stay with her, he wished he could wake up and have the bloody cat on top of him and Molly, half-asleep, making coffee for both of them. But it was no use being pampered while there was a fully-functioning criminal network on the go. Just as things were looking up, he had to leave for danger.

As he entered his mind palace, little bits of Mycroft's information and his own deductions floated in the air.

Jammu and Kashmir – Naachnaa (Terrorism)

Tibet – Aaliyah Chorum (highest assassin in network)

Hong Kong – Smuggling Ring (Black Lotus)

Somalia – Qoob-ka-cayaarid (head of a group involved with human trafficking, burglary, homicide and rape)

And London, the very heart of Moriarty's network, where Mycroft's men would be tracking down those who clients are "put in contact" with, who arrange everything until all Moriarty had to do was consent to the crimes.

The cab had been outside the airport for 10 minutes now.

"Mate, I know you're thinking but you might want to get out, I can't stop here forever," said the cabbie, tentatively.

Sherlock handed him the fee and stepped out onto the pavement. He made his way quickly through security and sat down by his gate. He sat and waited for a minute before his flight was called from the speakers.

"Flight BA0055 to Hong Kong is now available for boarding."

Sherlock stood up, and looked out towards where his plane was waiting. He could still turn back. He didn't have to do this, Mycroft could get his men to do it. Probably.

"Sir?"

Sherlock looked at the flight attendant. He was less than pleased about her rousing him from his thoughts of running back to Molly's flat.

"Yes?" he sneered.

"You've been standing at the desk for ages now, if you aren't boarding the Hong Kong flight can you let those who are boarding to get past you please?"

She smiled irritatingly as Sherlock handed her his boarding ticket and fake passport.

"Have a nice flight, Sir"

"I'll certainly endeavour to," he grumbled under his breath as he stalked off.

Almost everyone was on the plane and there were still plenty of seats at the back, it looked like Sherlock was getting his row to himself. As he settled himself into his seat and his thinking pose, a young girl and her mother sat down next to him. Just as things were looking up.

"Mummy, can I get my magazine and my sweeties?" asked the little girl in an infuriatingly high voice.

"Ellie, the flight hasn't even started yet. You'll be bored later if – "

"Pleeeeaaaaaase!" Ellie whined.

Her mother gave in and Ellie spread her elbows out, onto Sherlock's and her mother's armrests, so that she could hold it. She started giggling at whatever childish things were on the first page, she chewed her fruit pastilles loudly and she kicked her legs against her chair.

Dear God, it wasn't too late to turn back was it?
