Usual disclaimer

They split off, Claire on her own searching the floor of offices, and Rebecca with Billy to the labs on the second floor.
The offices were neatly arranged, the best way to describe it was like a noughts and crosses board, the rooms were isolated with the corridor around them. Claire slowly entered the first room, it was so tidy you wouldn't think that someone tried to flee apart from files scattered on the floor. Claire picked them up and looked through them, nothing of any use, pages were missing in some reports, the days that Steve arrived. She looked around the room, the desk was slotted into a corner with small bookcases either side, a bed was at the far end. It made sense that the scientists and researchers stayed in the facility, after all if they were spotted coming in and out of the complex when it was seemingly abandoned it would raise eyebrows...and curiosity. Leaving the room and entering the next one, exactly the same as the first, reports missing.

Rebecca and Billy were having a harder time, the labs were like a maze of short corridors and turns. They barely made it to the first lab before they got attacked by a couple of runners. They came across a few locked doors before hand, obviously due to the security override by the guy from the train. They all agreed not to release any of the assigned locked doors until they knew the other rooms and corridors were cleared of infected, not wanting the risk of finding out some monsters could open doors or any contained experiments were sealed within. The lab they did finally manage to get into was one of the larger ones, with three large workstations in the center. Glass cabinets had smashed on the floor, their contents spilt along the dark tiled floor.
"Should we be worried?"
Rebecca shook her head "It's been months since the outbreak started, if any of this was airborne material it would have left through the vents a while back."
The whole lab was a mess, the desperation to destroy any evidence against them was very clear. The fume cupboards in the corner had the remains of burnt articles, folders mainly, the sink had a vast array of colours staining it, they poured whatever they could.
"They know not to pour chemicals into the drains, that would have caused a major outbreak to densely populated cities either airborne or in the water. This must lead to somewhere else where it's safe to dispose..."
"Where the hell is it safe to dispose of life threatening chemicals?" Billy looked through one of the cupboards to find a handgun and ammo. "Looks like they were ready for anything." He held up the gun and examined it "If say the infected came in and attacked them this would have been no good, if Umbrella came in they would be shot immediatly...do you think that the lab guys didn't know about the advanced mutation?"
"Could be, the mutated were kept confined on the next floor up, they probably knew that they were working with the Veronica virus but didn't know it's capabilities."
They were too busy searching the cupboards to realise something had quietly crawled out of a fume cupboard vent.
They found a medallion of an ape "Oh great that brings back memories.." Rebecca sighed and stood up as Billy laughed
Suddenly she was attacked and flew into the corner of one of the workstations hitting it painfully on her left side, falling onto the cold tiles below.
"Rebecca!" Billy rushed to his feet, magnum at hand quickly aiming around the room to find the perpetrator. On the wall adjacent to them was something they had never seen before, it was huge. Billy couldn't understand where it came from, six long legs with what looked like sickles on each end, five white eyes, it wasn't very hairy, it wasn't a spider..an insect?..It still had a human shape to it. He fired two shots at it before it lunged at him, he rolled out the way and began to fire at the infected once more. Rebecca regained her composure, slowly standing, the adrenaline numbing the pain in her side she grabbed her grenade launcher and fired at the monster.
It fell after two shots from Rebecca, flailing it's legs and hissing as it's life ended, they approached it to try and get a better understanding as to what it was.
"You alright?" Billy put a concerned hand on the other's shoulder.
"I'm fine, the pain has gone, probably a nice bruise to match the scar" She chuckled, keeping her eye on the dead thing in front of them. "What the hell is this?"
"Well they were keeping things secret even from Umbrella..could be anything..but since they were using the prisoners as test subjects I guess we can sort of call it human...But whe-" Billy was slammed into the wall, his magnum fell from his grasp as another of those creatures had appeared and trapped him.
"Billy!" Rebecca grabbed her assault rifle, dodging it's flailing legs, it would have been easier to use the grenade launcher but she didn't want to risk hitting him. Moving to the monsters' side she raised her weapon and began to fire.
Billy was staring right at it, seeing the mouth gradually open to see it's menacing fangs. The mouth was sitting vertically, opening wider and wider across.
He struggled to escape as it's mouth drew ever closer to his face..it was going to rip his head off..
Rebecca was getting desperate, soon the man in front of her was going to die if she didn't do something. Without any hesitation she grabbed the fallen magnum off the floor and found a moment to fire a point-blank shot through it's head, she was expecting a lot of recoil, but it was powerful enough to dislocate her right shoulder.
The monster's head blew clean off and fell instantly to the floor, dead.
Billy helped Rebecca pop her shoulder back in, and picked up his magnum once again. "Thanks" He helped her back to her feet "Let's get out of here before more of them show up."

Claire found the offices of the four researchers that were assigned to travel from the mansion to the facility, Richard's room had been completely trashed, Trevor's was completely empty and Mike's just had a runner. She found Michelle's office, but unlike the others the door was locked, beside it was a keypad with a red light.
She placed her hand to the radio "Hey Rebecca, what was Michelle's security code again? I've found her office"
"56734TFRDMF"
Claire swiped the card an input the code only for nothing to happen. "Is there any other code that it might be?"
"There's MFMS63009UM"
Claire tried the number and the door blinked green "Great, that's it." She entered the room to find it clear and documents piled on her desk. "You guys been alright?"
"We found an Ape medallion, haven't found it's purpose yet, any files up here have been burned. Other labs have come up with nothing, few runners..and a new infected.."
"..A new one?" She stood over the desk and opened the first file.
"Was part human and some sort of insect, we don't know where it came from, but it was pretty big.."
"I'm thinking, maybe it came from the vents?" Billy had pondered that thought for a few minutes as they walked along the maze of corridors
"Could have been actually...Claire, they may be hiding out in the vents, be careful, and we've got incoming."
Claire left them to it and began to read through the files. Once again a lot of notes concerning the experimental, but others caught her interest.

January 6th 1999
That Regan guy has been creeping around, constantly wanting to know about 0267 and 6612.
I keep telling him I don't know, why doesn't he actually find the head researcher or scientist and ask them?
It's not like he has the authority anyway, just because he's Birkin's understudy.
I don't think he knows who 6612 really was.
He needs to know if he keeps sticking his nose in like Gareth did there will be consequences.

January 11th 1999
He's still here, I caught him trying to get into the containment level. Security finally chucked him out.
Albert just told us to keep an eye on him, but everywhere you looked he was there, something's not right...

"Why would Regan be snooping around the facility? Was he with Umbrella or not?" Claire put the notes to one side to show Rebecca and Billy later.

She brisked through a few more folders until she came to one titled Veronica - 0267.

Only a small handful of us know what happened at Rockfort Prison and Antarctica, Albert filled us in. He attacked the Island with the H.C.F to get the Veronica Virus.
He aimed to get it from Alexia Ashford, but found a young man who had mutated thanks to Veronica. He called ahead he said that we could experiment, take samples, anything we want from this body in return we help him topple Umbrella and create new foundations for him to lead the new world. How could we refuse? Umbrella never cared for us, we were the lab that were given the jobs no other wanted, the dustbin of Umbrella you might say. We have highly talented scientists and researchers put to waste so we jumped at the opportunity.
Samuel Regan brought us the person in question, patient 0267, straight from Antarctica and a man from Understock whom I vaguely remember visiting with Albert on several occasions. This man was to be the first Veronica test subject, but we used others too. We learnt that the Virus effects everyone in different ways 6612 and 0267 had adapted in their own way.
0267 in general was re animated thanks to the virus, yet when he was talking he wouldn't show us his mutation, Albert told us to mention the name Claire Redfield and that would get his attention. It did, the more we taunted him with that name the more he'd react. Soon it did get out of hand we had to send security and researchers in to calm him down...he mutated fully and killed them all in a second. It was stunning..a marvel! We have an ultimate bio weapon. We don't know what he's like when he's in his human form, all he did was sit on a chair all day doing nothing. Seems he doesn't have powers out of mutation. But then again, he may not be showing them.
Not long after finding out all the mutation data we used this for the experimental, the change in stature was incredible, it became much stronger. Sadly Gregory ended his life for our research, the battle stats were off the chart! We know that if Umbrella comes knocking we have the perfect weapons.
The Virus itself has shown massive mutation enhancements even in the basic infected. They grow more powerful everyday, their resistance is greatly increased depending on the type of infected and how the body adapts to the virus, their bodies could change depending on what we implant into them. This is turning out to be the ultimate, The T-Veronica type 2 Virus...might work out a better name later..It'll be the most feared out of the T-Virus creations, and we helped create it into something unstoppable.

Rebecca and Billy had one last lab to look into, they found the doors up to the containment level to notice they were one of the overrided security doors. This lab door was slightly ajar, alerting the two that there was probably something inside. Billy carefully checked it out whilst Rebecca guarded the corridor.
"Okay it's clear, and there are no vents or fume cupboards either so it's good...Rebecca?"
"Billy...help.."
He rushed back out the room the see her slouched against the wall, but she was not alone, in the distance three runners were coming for them, too much for Billy to handle on his own, he shot at least one to the ground and quickly picked up Rebecca taking her into the empty lab and slamming the door behind him. Laying her on the table he quickly took off her armoured vest and lifted her shirt to see the dressing over the experimental wound was soaking wet with blood, even dripping. Quickly removing it to see that some of her stitches had popped, not many but enough to release a steady blood flow.
"Do you know when this happened?"
Rebecca shook her head "The adrenaline from when I was thrown must have disguised it"
He lifted the shirt a bit higher "Tell you what, you were right about that bruise.." He rummaged through his backpack for his surgical thread and a fresh dressing "You keep doing this i'm going to run out of everything" He chuckled as he began to re stitch the wound. Rebecca could feel every needle incision, of course she was unconscious before, and the bruising isn't helping the situation. She rested an arm on the man's shoulder and looked at him, it was relaxing her, she barely felt anything after that.
Billy finished the stitching and placed a new dressing over the wound, he felt her fingertips slowly stroking the back of his neck and looked at her.
"No more being flung into things and powerful recoil weapons"
"I'll try, but I didn't do it on purpose"
He sighed as he helped her sit up on the table "I would like you to finish this mission alive..I nearly lost you before."
"Well you can't get rid of me easily, you know that yourself." She reaches to the chain around her neck and pulls it out to reveal dog tags "I have to thank my good luck charm.."
Billy looked closer "The one you ripped off me before we split.." he smiled "Thought you would have thrown them away after saying I were dead."
"Let's just say you made an impression on me, besides, thought you'd might want them back next time I saw you...whenever that was."
He held the tags in his hand and shook his head "Defiantly look better on you, keep them"
She held his hand and pulled him closer lightly brushing their lips together. Billy was taken back for a second but finally let his feelings be known to her. He cupped the side of her face and softly kissed her lips.
