NEW STORY woop woop! I was inspired for this story from another fic I read called "Rule Number Five" ( s/8946023/1/Rule-Number-Five) which is a great piece written by ttiiggeerr so all credits of the story idea go to her!
Please review if you liked the idea and/or story and I'll hug your socks off! :)

Dan was perched on the top of the building and he was waiting silently to hear the quiet footsteps in the darkened alley. He knew that this was the location of most of Mihn Ha Fikoshi's drug deals, and he was determined to make this hit, so he could make it back to London and his beloved Phil. He stared down into the darkness and used his keen eye to make out the figures below. He heard a click of a lighter and smelt the all-too-familiar smell of cigarettes. As he positioned his weapon to pierce right through Fikoshi's neck, he took a moment to revel in that feeling of power and rush of adrenalin he always felt right before a kill, he put his finger on the trigger and squeezed down carefully, keeping his hands completely steady. As the poison dart was impaled right through Fikoshi's neck, Dan was out of sight and scaling the other side of the building before any of them realized what had happened.

He dashed though the Tokyo streets, steadily taking off his black clothes and changing into more civilian-looking clothes. He kept his gun at the ready, just in case anyone decided to come looking for him, after finding out who he was through the Computer Links. The agency had tried as hard as they could to keep all the assassins off of the Computer Links, or even hidden some way, but even the best of the hackers at the agency couldn't get into the system. Everyone's details were freely available on the Computer Links, so there was no real way of hiding yourself, even in a foreign country. Your best bet was just to give the bare minimum of information, no more, no less. Forgetting all this, Dan had commandeered a vehicle and was his way to the airport to board the jet that would take him back to London and his own life.

Dan was ultimately two people, the man he was at home, with Phil. Where he enjoyed video games and Chinese food like most people, but when he had a mission, he's away for weeks or months on end, as was his partner, Phil. Sometimes, when Dan would eventually get home, there would be no sign of Phil. It's not like he could just leave a note saying "Just popped out to torture a Russian drug lord, be home in September, xxx", because obviously, they were spies and that wouldn't be very inconspicuous now, would it? Dan tried to be strong but there were some days when he would just break down and cry, hoping to a god that he didn't believe in, that Phil wasn't dead. Phil was the only person in the world he ever loved, and he was the one person that Dan would think of when he was being held captive in a cellar, having glass smashed over him, being cut open and bashed. Phil was the reason that Dan always pulled through, tried every type escape route and Phil was the person Dan saw in his mind when he was running for his life through a desert in Australia, desperately trying to get back to civilization before his life signs faded completely.

Other times, Dan would wake up screaming for Phil for run or wake up with a tear stained face, after having nightmarish dreams about Phil. The best nights were those that Dan could lay back down and see Phil beside him. Or the nights that Phil would wrap his arms protectively around Dan and not let go, and they would just stay in bed together watching re-runs of their favourite shows while being wrapped together under a warm doona. But as Dan made his way into the dark apartment, all these memories faded and he checked for signs of people hiding inside the apartment. They had the best security systems available and there was really no way that anyone could get in without being shot, but Dan always wanted to be cautious. As he cleared each room, a sigh of relief washed over him but it was accompanied by a feeling of melancholy, because he knew, if all the lights were off in the house, Phil wasn't there. He made his way into the dark living room and stopped instantly as he saw a dark figure curled up on the sofa. Even though he thought it was Phil, he decided to be vigilant anyway, as someone could be acting. As he got closer, there was no mistaking that it was Phil; he could see that he was asleep – or passed out – so he was quiet as he curled up next to him.

The second that Dan touched Phil, Phil jumped up and pulled his gun on the intruding party. Before he pulled the trigger, he saw that the face at the end of the gun was Dan, and he dropped it instantly.
"Dan?" Phil said.
"Yeah, it's me." Dan said, stepping towards Phil and putting his arms around him. Dan felt Phil start weeping and he squeezed his tighter.
"I was told that you were dead." Phil said seriously through his tears.
"What?!" Dan said, as he stepped back from Phil
"They…they said you weren't on CL anymore and they couldn't find you. Did you check back in after your mission?" Phil said, wiping away tears with clenched fists.
"Of course. Did you check CL?" Dan said, moving over to the in-wall computer which displays Computer Links.
"I did. You're not there Dan." Phil said with a hint of anger in his voice.

As Dan clicked onto CL he realized that he was indeed, gone. He turned around to Phil and flinched at the arsenal of weapons he had within his reach.
"You know what this means, Daniel." Phil said darkly.
"Unfortunately," Dan said, "yes."
