The hardest part must've been to fall asleep while stranded on a chair with an open wound. Her cybernetic enhancement could only do much to repair surface tissues, but they were not powerful enough to heal a stab wound.
Waking up seemed even worse. Her muscles were sore, she couldn't stretch herself, she couldn't rest very well and her leg felt even worse, with a felling of intense pain whenever she tried to move it a bit. She felt weak and sick but mostly, she was thirsty. She didn't realize that she hadn't drink any water for a day already and only now did she started feeling the consequences.
She was still in the same room, but she wasn't alone. Someone was at one of the table, preoccupied by whatever was on it. Angela took some time to regain all of her senses and notice a weird smell, she hope it wasn't her wound.
A glimpse to her right revealed what that smell was : a large, fresh piece of meat was hanging from a hook next to her, slowing spinning on one side, then the next, with a large open cut in the middle of it.
She could hear some mumbles in front of her, with the person at the table talking to themselves, although she couldn't make out the words, they seemed to be in spanish.
She could identify a woman once again, but thankfully it wasn't Widowmaker. Instead, the vibrant purple color on her head reminded her of the girl who had caught her in the hospital. She was young, younger than her at least, and seemed to be working on some sort of…
Her Caduceus staff!
What was she doing with the entire staff? She clearly left it at her house in Numbani. All sorts of emotions passed through her with the vision of her healing device. The girl got up and tested it out : a short beam of light got out and searched for a target only to be deactivated. « Asústame, Panteón. »
She went to the piece of meat and activated the beam only to see it quickly recover the large cut in the flesh. « ¡Ja! ¡Me la rifé! »
She turned around and noticed Angela starring at her staff. « Oh! You're awake! »
The girl leaned onto the staff and looked at her from head to toe. « Ay, pobrecita. They really messed you up now, did they?
- Who are you? she mumbled as an answer.
- Let's just say that I work here, alright? Look, no hard feeling about the hospital. I was doing my job and you were doing yours. »
Angela frowned her eyebrows, who was she to talk about horrible things like that just like… « No hard feelings? You… you murdered people.
- Now me? I only hacked the system. It was the boss and the others who shot people down. I was doing my job.
- You helped them. They got in and killed hundreds of people because of you. Elderly people, sick people, women and children. The EMP killed hundreds of staff members.
- The EMP didn't kill everyone. I know, I'm the one who did it. It was a small one that shut them down for a few minutes.
- Don't you understand that these people died because of you?
- I do, but I got used to it. People die everyday, even more people died during the Omnic crisis.
- Those people were innocent.
- No one is truly innocent, you know. Plus, we didn't kill that many people, most of them were just injured. I think you are making this into much more that what it is.
- How can you talk about bombing a hospital as if it wasn't much?
- Listen. I do what I have to to survive. I've done worse than that and many other would've done even more damage. We needed you, we went to get you. If you knew you were in danger, you shouldn't've hid inside a hospital.
- You're a monster…
- Eh, I've heard worse. »
She got to the table and wrote down some notes on the table. « Plus, if the hospital had a better security system, they would've gotten away with it. Same goes for your staff and your equipment.
- You stole that from me.
- Who thinks of hiding such powerful technology behind a five number security code? You know, any computer with the worse kind of hardware could've figured that out in a few seconds. You're lucky I'm the one who found it first.
- Lucky?
- Yeah, I'll now how to use it at least. Plus, now you know where it is. Imagine coming home and some random guy had broke into your apartment, stole all your stuff and just sell it for a high price. You'd never find it again. »
That girl sounded so overconfident in everything she said, Angela couldn't stand her and her casual ways of talking about such horrible things. Now she had her Caduceus staff and she had no way of knowing what she would do with it. Did she also had her Valkyrie suit? She had a spare one hidden inside her apartment which, she had figured out by now, had been sacked.
« Plus, you're also pretty lucky that the boss wants you. You know why I'm working out your staff? The boss wasn't very fond of what Widow made to you. He asked me to find out a way to make your staff work so that we could heal you and all.
- Give it to me and I'll make it myself.
- Ha! You really think I'm gonna fall for that? I though you were a genius scientist. But again, if you hide your stuff with such weak security… »
She finished writing her note and got to her. She kneeled to see the wound on her leg. « Well that sucks now, does it.
- You act like you're so much better than everyone, do you?
- Now hold on, you're the one who's strapped onto that chair, you know? »
She touched her wound which made her cringe and pant. « Yeah that looks pretty sensitive. Let's just hope it didn't get infected or anything.
- It's not. » She said, knowing her enhancement could at least clean up the wound.
« Well, let's try it out then, » she said while pointing the staff at her.
She sent the beam of yellow light which englobed her leg, found the wound and proceed to quickly close it. Angela could feel her leg become numb as the nerves were shut down around it by the nano robots. A few seconds later and the wound was closed, leaving only the dried blood leaving a brown trail all over her leg.
« De pelos , the girl said. I wanted to try it on me first, by cutting my arm or something, but I was to afraid that you'd trapped it with something like fingerprint recognition, so I spend the night neutralizing all the security system from it and now, it's mine.
- You don't deserve to use such tools.
- If I know how to use it, then I have all the rights to do so. »
She got back to the table, then said. « Also, I don't want to be this kind of girl, but you know what that staff means right? »
Angela frowned and the girl said. « Basically, Widow can do all the things she wants to do on you and she'll be able to heal you up and act as if it never happened. »
He heart stopped for half a second at that though. They were using her inventions against her. « Well that is, of course, if I let her do it, you know. Here's what I'm trying to tell you. According to the boss, you're not dying in here, but you are going to suffer. I'm not like them, or like anyone here. I'm ready to have a little chat, you know? »
She went back to Angela, leaving the staff on the table, and kneeled to be facing her. « I've heard a lot of things about you, Mercy. Lots an lots of good things. You're the kind of person that people would want as friend. It just so happen that I really like making new friends. The deal is simple. I don't let them use the staff to hurt you and in exchange, when they'll eventually release you, we'll keep contact. Who knows if you might get a second staff, after all, I am good with technology. »
Her eyes were the one of a thief, a girl that knew she had everything under her control. « I won't be making any deals with terrorists like you, Angela claimed, with anger in her voice.
- Is that so? Alright then. Let's hope they won't go too hard on you. »
She got up and went back to her table. Angela got all the energy she had left to say firmly. « I need water. »
The girl looked at her and sighted. « Of course you do.
She took a water bottle and brought to her, uncapped it and brought it to her lips, only to stop right in front of her and say : « Actually… »
She held the bottle on top of her head and forced her to look up to the light. « Open up and say « Ah. »
That girl was treating her like an animal, but she needed the water, she did as she was told and receive a slim stream of water. She felt refreshed and better while the girl simply answered. « Mucho mejor. Now remember, my offer is still up. »
She finally reached down, looked her in the eyes and added. « Call me Sombra. » She then got back to her table, put on some earphones and blasted some music that Angela could hear all the way from her chair. At least she wasn't being tortured this time.
