Highly spin-off. Read for what it is, not what it might be...

Alex heard footsteps hastening towards him. The sound of the boots was slightly softened... reminding him of the specially-designed SAS boots he'd been issed with once or twice. Soft enough to dampen sound and provide protection but tough enough to run over a board stuck full of nails.
That meant these were most likely professionals, and not just aliens with violent tendancies.
Shit.
Alex pressed his back to the wall and edged towards the corner, buckling his knees slightly to gather strength. At the last second, just as the tip of the first man's boot began to clear the edge before him, he struck.
One hand gripped the barrel of the assult rifle firmly, forcing it up and away from himself. His first glimpse of the men counted eight bodies, plus the one he was attacking - so he made sure the ninth man's body shielded his own. As his left hand continued to force the barrel skywards - he'd have only an instant to pull this off, before the larger opponent recovered from the suprise and forced it back down again - his right hand bit towards the arm supporting the weapon. It was a move he'd studied under Scorpia, but never had the opportunity to try out in the field.
It worked, though. With an audible cracking noise the man's arm dislocated at the elbow, the joint forced apart. Main grip thoroughly broken and weak with sudden pain and shock, the man didn't have a chance to resist as Alex's left hand forcefully ripped the gun from slack hands, shifted it into firing position - braced against the crook of his own elbow - and aimed it at the rest of the group.
As the man he'd assulted staggered backwards - only a bare handful of seconds had passed - Alex caught a glimpse of movement from the undamaged arm. Realising that the man was going for his handgun, Alex kicked out. He caught him on the knee, right next to the kneecap. It was a lucky shot, as the man had aready begun bending the other knee in order to drop under Alex's firing level.
Having his second knee kicked out from under him, however, sent him sprawling. Alex snatched the half-unholstered gun with his right hand, dropping to one knee in order to be able to press it into the base of the skull of the man on the ground and still be able to aim the assult rifle with his left.
He didn't know what he was going to do next, however... He'd acted on instinct, up till now. If the others made an aggresive move then he knew he'd open fire and deal with the consequences later. If they surrendered....
What would he do then? Lock them up somehow? Scorpia hadn't been a fan of non-lethal solutions to tense situations.
"HOLD YOUR FIRE!" Someone roared.
Everybody froze. The man under his gun was breathing harshly in pain, but remained utterly still. The men before his rifle had instinctively ducked or dove to the side when he'd appeared, but he still had a good chance of hitting them all. The hallway wasn't wide, and with the gun not properly supported with both arms it was liable to jerk around quite a bit when fired.
The man who had issued the command took two steps forward. Alex centered the rifle on him, his heart beating hard and fast in his chest, his every sense sharp and almost surreal in it's awareness.
The man spoke, voice wary and tinged with disbelief.
"Cub?"
Alex blinked.
His eyes flicked from body to body, his hyper-awareness fading away to let reality slip back in. The bodies stopped being bodies and started being people. Four of whom he recognised.
He locked eyes with Wolf - the man who'd spoken.
"Shit..." He breathed, half in response to the situation and half in incredulous disbelief himself.
It was with a wry twist to his lips and a watchful look to the rest of the SAS men that he lowered the rifle and removed the gun - clicking the saftey on automatically.
"Wolf." He acknoledged back as he stepped up and away from the man on the ground - just in case the guy got any bright ideas to do with back-up guns or knives. As he did so, Wolf gestured quellingly to his comrades. The men lowered their own weapons - four of them clearly reluctant to and three of them with faces almost as astonished as Wolf's own.
"What are you doing here?" Both asked simultanously. Both frowned, Wolf more darkly than Alex.
"I wasn't informed that there was an agent in place." Wolf set out suspiciously. Alex half-shrugged.
"Yeah, they probably don't know. About half the jobs I've done for them were things I fell into unintentionally... and all of them were unofficial." He paused. "Uh... no offence, but.. Are you actually aware of what's going on in here?"
Wolf's frown darked into a scowl.
"Suspected terrorists instigating a.." He cut off as Alex shook his head almost immediately. The teen reversed his grip on the rifle, clicked it's saftey on too, then tossed it at Wolf. The man caught it in one hand.
"I don't have time, then." Alex explained simply. He turned slightly to the man who had pulled himself up by now and was cradling his arm. "Sorry." He apologised shortly, but with audible sincerity, before turning on his heel and heading back to the door-panel he'd been trying to open right before hearing them stampede towards him.
He heard a couple of voices behind him, as one man he didn't know hissd an incredulous "Agent?" to another and recieved a just-as-incredulous reply. Wolf's voice cut over them both, however.
"Cub!" The man's voice was hard and demanding. It was clearly not going to take being brushed off so easily. Unfortunately for it, Alex didn't have time to introduce them to their new sci-fi-ish reality.
"I can't tell you what's going on, Wolf, because you honestly wouldn't believe me." Alex turned slightly, looking at Wolf from over his shoulder. "MI6 has trouble believing me about every-day things like bombs and biological weapons so this.. is not something I should waste air on. I will tell you, though.. Everyone in this building except for your people, myselfe and my companion, are 100% enemy threats. Shoot first and ask questions later. I assure you, those questions will explain everything."
Alex kept walking, not stopping a second time when Wolf shouted after him again.
He rounded the corner and took the several steps down to the door.
The open door.
The open door which featured The Doctor leaning against the frame.
"Hi." The Doctor greeted at about half-cheerful as usual. He looked vaguely troubled by something. Had he seen the incident in the hallway? He knew the Doctor didn't like violence.. when it could be avoided. Would he be repulsed by him now? After a moment, Alex realised his eyes were locked onto the gun still held in his hand. Swallowing, he checked to make sure the saftey had remained on, then jammed it into the waistband of his jeans. He turned apprehensive eyes back up to The Doctor. The other man - the alien - was now studying his face just as intently as he had the gun, eyes still troubled.
"Friends of yours?" The Doctor asked, jerking his head back towards the audibly-arguing men. Alex nodded, then caught himself and shrugged, before hesitantly nodding again. The Doctor's lips twitched a little.
"Oh good. Well, we'd best be off, don't you think? Seeing as we only have about nine minutes left?"
Alex nodded and followed the Doctor back through he doorway, shutting it behind him just as footsteps rounded the corner. The Docter reached back and locked the door again with his sonic screwdriver. "Don't need that lot getting underfoot." He stated - apparently to nobody - then grabbed Alex by the arm and dragged him off into the labryinth passages.
