Chapter 20

(Leon's POV)

Once everything was settled we looked at Kathleen who was standing with Rebecca talking about something and we approached her, "I don't get it you killed him then how exactly he came alive?", Rebecca asked referring to Frank.
"I punctured his diaphragm, the plaga was still within his body; being a parasite along with t-virus it wasn't able to gain full control and was in semi-dormant state, till they gave it a regenerative property, so that his punctured diaphragm is repaired and he came alive with the help of T-virus", she explained, "How's Ada?"
"She is already in induced coma", Rebecca said, "I think it's hard for her to survive now."
"I know, I wanted to perfect the cure but there was no time, she was getting violent everyday plus they kept increasing her dosage", Kathleen told her and she seemed a little concerned.
"How do you know?", Rebecca asked.
"I am just guessing, since she hadn't killed in a long time and she killed two men this time", Kathleen answered in her old familiar tone, "Wesker might have given her something to suppress the urge."

"Wesker is still alive?", Chris questioned, "I mean, didn't you kill him last time?"
"No, he survived", Kathleen told him, shaking her head, "I could just slow him for a while and he played possum, so you took him to be dead and then I was stabbed by my father before I could deal with him", she explained.
"Don't worry honey, this time he'd die for sure", Jill said determined, keeping a hand on Chris's shoulder.
"Only if we managed to kill him the right way", Kathleen said.
"And what's that?", David asked.
"The same way we killed those two BOW", she replied with shrug.
"You gave them the cure", Claire said.
"No, actually I sort of overloaded them", she said, "the same type of kill that you guys have been witnessing around the town."

"So you're telling me, you really killed them", John asked in disbelief.
"I don't intend to kill people unless it's too late", she answered in a serious tone.
"Then those two BOWs?", Jill queried and she shook her head.
"Then who, I mean, who can so brutally murder people", Rebecca said puzzled.

"It was Ada", she said sadly. It seemed she didn't harbor the hate Ada harbored for her, "To be precise Ada killed the men and then either Frank or Tiera made it look like they were stabbed, but I guess you might have figured out that much."
"Ada? But why?", I asked, "And did you know from the beginning", she nodded.
"It's because she was not getting what she wanted", she said in an obvious tone.

"So you are telling us that you didn't forget anything", Jill asked the very question I wanted to ask her from the moment it was revealed that she remembered her old self.
"No", she replied, "I remembered everything."
"Then why you did pretend to be an amnesia patient", Claire asked and she seemed hurt a bit.
"Because I had to keep an eye on Ada's primary target", she replied.
"Primary Target?", John repeated bewildered.

"Uh… huh… Leon", she pointed at me.
"Me?", I almost yelled in surprise, "I thought she loved me, why she wanted to kill me?"
"She didn't want to kill you", she replied slapping her head in frustration.
"So what are you suggesting that she kills her secondary targets and loves her Primary target", John said in an obvious tone.
"No she didn't intend to kill anybody", Kathleen sighed in distress, "Look the thing is that Wesker wanted to get an ultimate bio-weapon."
"Tell me something new", Jill said rolling her eyes.

"Well while he was studying the hybrid T-G virus, he got this idea of merging the abilities of all viruses in one. He began experimenting and he created Frank first, he was hybrid between t-virus and las-plaga but when he tried to merge more viruses or parasite in his body; Frank's inferior body could not take the load so he had to stop in between G-virus merging", she explained.

"And if it wasn't for t-Virus and plaga parasite then he might have been dead right", Rebecca said excitedly.

"Yes, I saw you figured that part", Kathleen said smiling a bit, "Okay so now he was faced with a dead end and everybody hates dead end don't they? So he started searching more and more; but that's when he was faced with you two", she pointed to Jill and Chris, "and with your somewhat stupidity, I must say, he was able to get his hands on Jill, the one infected with T-virus by nemesis and his curiosity made him experiment on you and you were able to bear all the experiment he did on you due to your superior blood type more correctly genetics. He was on the process of doing same to you but he needed more information and that's what made him unlucky because due to your luck Chris and Sheva managed to save you from him."

"You mean I would be one of them if they didn't save me", Jill asked.
"Probably", she replied nodding.
"So how he managed to get all the viruses fused then?", Claire asked.

"Well he tried to study more if he was missing something and while he was doing that, he came across Dr. Ashford's notes and how he managed to create his twin son and daughter Alexia and Alfred Ashford by injecting the gene of wisdom in an embryo, and the notes from Alexia herself that she needed to be dormant for 10 years or so to incorporate t-veronica virus in her body fully. So he was struck with the thought that nature is better creator than man, so the only way to make nature work for him was to meddle with the life processes", she said and I think I was not the only one, who had difficulty in understanding the last part.

I was about to ask what she meant but John beat me to it, "I didn't get a thing."

Kathleen smiled again, "I was just beginning hold your horses. So where was I? Ah… yes meddling with the nature. So he began experimenting again to fuse all the viruses separately to inject it into some developing embryo but, he was again met with failure again because of the overloading thing and then he was reminded of your superior genes and how the experiments were successful with you. So the he made the conclusion that humans with superior genetics are able to withstand more infections as compared to others. To prove his theory he tried to experiment that on Tiera, her superiority lies somewhere between, so she was able to incorporate las-plaga, nemesis parasite and g-virus but further infections were killing her. So he needed more superior beings and that is when we destroyed his base where he was keeping his specimens. Ada got hurt badly and went into coma, a superior being in dormant stage, perfect chance for him to fuse the viruses in her body."

"So he kidnapped her", I concluded.
"Yes and successfully fused dormant inheritable viral genes in her", she said thinking, "He was able to put all viruses' genes in her but it doesn't mean they were able to cause mutations in her, she was just a carrier. His one third of plan was successful, for the rest to be successful he sent her back."
"What was it?", Jill asked.
"You know, how in farms to get better produce, a superior male is mated with a superior female, to get a more superior being", she explained further.
"What are you saying?', Claire asked.

"Well to get a superior host that could incorporate properties of all the viruses, it's necessary that the being gets them through inheritance, birth cycle. A bio-weapon so produced is far superior than any of he could create. I mean as I said earlier nature is far more better creator than man", she said, "But still it had to be produced by a superior male and female otherwise other wouldn't be able to take the load of the virus even if they are in dormant stage, they are harmful. So he sent her back in search of a superior being. I mean Ada just can't get a child by her own, can she", Kathleen said in a matter-of-fact tone, "And that's where he comes in", she pointed to me, "Her primary Target, the superior male."

"You have to be kidding me", John said faking a jealous tone, "Leon has superior genetics."
"Yes like most of you", she said looking from one face to another.
"Yes", John said happily, "I am superior."
"I am talking about genetics", she said to bring him back to the ground from the clouds of happiness.
"So you're saying she could have gone after any of us", Chris asked.
"Not exactly", she replied, "Leon has a priority over you guys since he was infected once and was an excellent host to las-plagas, and since the defense systems keeps a memory of old encountered infections he's was the right superior male for this job since the memory cells are nothing but attenuated virus cells. Plus he is the only one, whom Ada can get her hands quickly and easily, since he holds a soft spot for her."
"So is he a carrier then?", Rebecca asked.
"Yes, anyone of you who have been infected before is sort of a carrier", Kathleen replied.
"So we pass this to our kids", Jill asked worried.
"Yes and No; in your case the chances of off-springs inheriting viral genes is very probabilistic, its 15-20% chance but its 98-100% chance in Ada's case", Kathleen replied.

"Okay, so why kill other men", Claire asked.
"She didn't kill them on purpose, like I said before if she go out and seek other than a superior male, they are dead because of the viral infections… and before any of you ask why she did that it was because Leon wasn't giving her much attention, so she took it out on others. It was something like an animal instinct."

"So why did she tried to blame you of all the murders", Chris asked.
"Didn't she yelled it herself that she hates me and stuff", she replied too lightly.
"Why didn't you tell us this all from the beginning", I asked her, moving close to her.
"Would you have believed me?", Kathleen asked, looking up at me with an amused expression and in an almost mocking tone, "Oh I didn't know, next time I'll definitely tell you. You know I just thought if you didn't believe your love of a lifetime, how could you believe a cold and inconsiderate bitch?"
"If you came early than Ada and told us about her being kidnapped and all, we would have believed you", David said seriously.
"Look Wesker started working on her the day he got her as his test subject, and if I had come to you, I know you had to follow a procedure, get authorization from god knows how many people; so I just decided to go alone to get her out before anything serious is done to her but Tiera spotted me and almost killed me but I was able to fool her. I had to remain in hiding because I was half dead to come to you. Only after I saw the news I hired two people to pose as a couple to bring me here."

"Why fake of amnesia then?", Claire rounded of the original question from where everything began.
A sarcastic laugh escaped her lips, "If I hadn't done that then he might have gotten laid by now and the ultimate BOW host, might have been on its way", she said a bit monotonously and as coldly as one could say, "If I hadn't competed with Ada for his… his… his", she seemed a little lost with words, "love?", she sounded a little unsure, "then only God knows what would have happened?"

"Why were you sure I would pick you", I asked her.
Another sarcastic laugh escaped her lips, "Honestly speaking you didn't pick me; you picked her every time. It was a cumulative guilt conscience that made you bend towards me. It was only after I faked to slip in coma, wasn't it?", she asked raising her brows at me.
"How did you fake that?", Rebecca asked, even before I could respond to her.
"Pressure point technique of course", she replied turning to look at her.
"So you wanted me to love you", I asked her and everybody looked at me, since it was a bit personal question. She opened her mouth to answer but before she could say anything there was a huge sound of a blast.
