"So you are from Zurich, Switzerland huh. That's a nice place I presume. " Medic said as they chatted. "I was from Rottenburg in Germany. It was a nice town, my mother was born there."

"So how did you end up all the way here?" Mercy asked.

"Well, I was a doctor and after the war I had trouble finding a job. No one wanted me as I lost my medical license. So I went over here to find one." Medic said.

"How did you lose your medical license?" Mercy asked curiously.

"Ze called me unethical or something.. Those people can't stomach real science. All I did was take a person's skeleton out to study it. I was just borrowing it. He just woke up before I could return it and complained a lot." Medic said with a slight laugh. "Funny really, ze were experimenting on all the Jews and dared to call me unethical ha."

"Are you sure you are not crazy at all?" Mercy asked slightly put off by the idea of a missing skeleton.

"Sometimes I wonder. But I don't think so." Medic answered. "Now what's your story Dr. Ziegler?"

"Well, I had a fairly normal childhood. In medical school, I excelled and was head doctor of the hospital as soon as I graduated." she started. "I was 17 when I managed to use nanotechnology to help in healing."

Medic was visibly impressed. "17 years old? I'm impressed. I was only 36 when I had a working prototype of my medigun here. And that was a chance accident."

"It took many long nights and technology has improved a lot over a century." Mercy said. "Shortly after that, the Omnic crisis happened. The UN drafted a special task force called Overwatch to handle the threat. They did really well and after it was concluded, they began as an international organisation dedicated to helping the world."

"The UN is still around that long?" Medic asked. "Hmm… I expected it to break apart soon. Countries just can't work together. We seen it with the League of Nations after World War 1."

"Well, things changed. Anyway, they noticed my work and invited me to join them. And there I worked as Chief of Medicine until they shut down." she said

"That a rather interesting life." Medic said. "So I assume that your healing staff is the product of your discoveries?"

"Well yes. It engages a stream of nanobots and some chemicals that accelerates the healing process." Mercy said. "Could you explain how your medigun works?"

"Well, it also projects a beam that is derived from a special concoction of chemicals. It does the job fairly well. The only issue with it is unless it is exposed to blood, it remains inert. So I need to harvest it from enemies to keep it running."

Mercy turned a little green at the thought of it. "Is that what that saw with the large syringe is for?" she asked.

"Very observant!" Medic said, oblivious to her disgust. "And if I add in more and electrify the mixture, it can turn someone completely invulnerable to anything. I tried to find the limit. Giant sawblades, a locker full of high explosives, falling into an industrial grinder, letting they pyro have a go at it. Did not work." he explained. "I'm been recently working on reviving someone after they died but I ran out of testing materials."

"Resurrecting someone from the dead?" Mercy asked. "I managed to find a way to do it. Only issue is I could only do it on someone who just recently died."

"Fascinating... How does it work?" Medic asked.

"Well, it complicated but the basis of it is that when I activate it, it will infuse the being with a huge burst of energy alongside a larger dose of the nanobots and chemicals in my healing beam. There is a limit though, it can't work on people who has been dead for more than two minutes and if they had suffered heavy physical tissue damage." Mercy explained.

"So like blown up chunks?" Medic asked. "Verdammit, guess that still can't save Soldier from his stupid rocket jumps."

"Rocket jumps? You mean explosive-based propulsion. That sounds dangerous." Mercy laughed.

"Oh, you have no idea." Medic muttered.

…..

They chatted till sunrise. Medic was the first one to notice. "Morning already? I'm late."

"Late for what?" Mercy asked.

"You'll see." Medic answered as he began rummaging through his cabinets of vials. After picking one up, he beckoned her to follow.

The headed down the corridor. Rounding a corner, Medic headed to the kitchen. He went to the back of the kitchen where the pantry was located. Opening the door, he headed in. The whole time Mercy followed suit.

Medic flipped on the switch for the lights. He looked around. "Ah, there it is." he said as his eyes rested on a large lunchbox. On it were large crude words written on it. It read Heavy's Sandvich. Don't touch. Or I will kill you and kill you and kill you scout. Medic opened the box and uncapped the vial he got. He began pouring the solution over the bread in the box.

"What are you doing? Mercy asked with concern.

"Nothing much. This is just a purified version of the solution my medigun uses. Heavy likes to eat his sandwich when he becomes injured or to feed it to us when we get hurt. He thinks it heals because his recipe is special but the truth is it only heals because of me doing this." Medic explained. "He do make tasty sandwiches though."

"That seems wrong to trick your teammates." Mercy said

"As long as it means that there is someone who can keep me alive I'll do whatever it takes. Engineer's dispenser can heal but it takes a long time to set up. So it is unreliable." Medic said nonchalantly as he place the empty vial back in his pocket and closed the lid of the box. "It's my turn to make breakfast. Can you pass me that container of pancake mix?" he asked.

"I'll help you make breakfast." Mercy said.

"Thanks."

…

An hour later, the other mercenaries filtered into the dining area. The smell of pancakes filling the room.

The first person to come in was Spy. "My my Medic. Your pancakes today smell better than usual." he commented as he came in.

"Thank the new person for it." Medic said as he looked up from the eggs he was frying. "She's a better cook than I am."

"Hmm, had a good night together huh?" Spy asked.

"Yes, in a non-perverted way you pervert. How long till you are going to admit you are scout's father?" Medic countered.

"He he, you know Scout was born before I met his mother." Spy smirked. "Miss Pauling called. I'll explain over breakfast."

"Finally." Medic said.

…...

During breakfast, Spy explained the task given. They were to head towards a nearby foundry and claim it by force for one of their clients.

"Now then. Any questions?" he asked.

"Question! What are we going to do about her." Soldier pointed at Mercy.

"Me? I don't mind staying back here." she offered.

"I'll keep an eye on her for you all. You know, to make sure she don't go anywhere she should not be..." Scout offered.

"Nice try Scout." Medic said. "I suggest we bring her along."

"You sure about it Doc?" Engineer asked.

"She can heal. It's good enough." Medic said

"You willing to go in da battlefield laddie?" Demo asked

"If I don't have to kill anyone. I'm ok with it." she said.

"Guess that's good enough." Engineer said.

A loud bellow came from the kitchen. "Who touch sandvich?! Scout!"

Scout's face turned pale. Heavy stomped into the dining area, him clearly enraged.

"It wasn't me." he said as he began to back away.

"Heavy is going to kill you now." the large russian man said.

"Com'on heavy. Why do you always think it's me. Why not the new nurse here." Scout made a last attempt at not being chased.

Heavy looked at Mercy, then at Medic who gave a shrug. "Heavy think little doctors did not do it. Now Heavy is going to squish you." he said as he began walking towards Scout.

"Ahh crud…" Scout said before he turned around and ran. Heavy quickly giving chase.

"Must have not closed the lid properly just now." Medic whispered to Mercy, she who was giggling at the events that just played out.

After breakfast, (and patching Scout up after being twisted up by Heavy) the group piled up into a old fashioned truck. They drove up to the foundry and parked the truck behind a boulder.

Spy unfolded a blueprint. "Gather everyone." he beckoned.

After everyone could see the map, he began. "We are currently here." he said as he pointed on the blueprint. "The gates ahead of us leads to the train yard in the middle of the compound. After we secure it, Engie you set up there to lock the area down to stop reinforcements from flanking us. Demo and Sniper and I will help defend. Heavy, Medic, Soldier stick together and push the first half of the base. Scout, you help scout ahead and to report enemy fortifications. Pyro. Just go and have fun." he looked at the team. "Oh right, I almost forgot about you doctor…"

"Zeigler." she quickly finished for him

"Right...you can stay with Engineer and Demo. Try to not let the guards see you. You are hard to not miss with that outfit of yours." Spy said.

"Duly noted." she said.

"Alright then, let's move out." he said.

…

To the guards on duty at the gates. The first indication that they were being attacked was the salvo of rockets hitting their guard posts courtesy of Soldier. The mercenaries quickly ran through the gates and into the train yard. There, there were several civilian workers and some armed guards. Sniper quickly popped a few of them while Heavy began firing on the others who had taken cover behind some crates. Unable to move, they were easy pickings for Demo to shoot a few grenades behind the crates. With that, the train yard was secured and Engineer began setting up his sentry gun and dispenser on the platform in the middle of the yard.. By now, the rest of the compound had heard the gunfight and they were expecting to be converged on soon.

Heavy, Medic, Soldier and Scout began heading towards one of the two buildings where the furnace is. Meanwhile, Spy went invisible and headed towards the other side to begin harassing the reinforcements. Pyro wandered off towards the direction where Heavy and they all were going.

The sentry gun constructed and began to scan the surroundings. It swerved towards Mercy but it did not shoot her. Instead it seemed to scan her before it rotated back towards the direction it initially faced and unfolded it's chainguns and a rocket launcher.

"Sorry if you thought my sentry gun was going to shoot you for a moment. but I did not have a chance to do a proper scan of you for the sentry's database." he apologised.

"It's fine." she said. She remembered how fast the sentry gun had shot her and felt caution around it.

"So, Medic tells me you are from the future huh. Well, could ya tell me how it's like?" he asked after deploying his dispenser.

"Well, we have what I think would be in your sci-fi movies. Hovering cars, holograms, sentient AI." she started. " There is also hard-light technology, sonic weapons and we had a lunar base before it was taken over by genetically modified intelligent gorillas."

"That's sounds real fancy." Engie said. "And ah though my creations were way ahead of its time."

"Well… to be honest, your turrets reminds me of the ones my friend builds. He struggles to have a working rocket launcher permanently on it." she said

"Ain't that a bummer. I would like to meet him someday, maybe ah can help him with it." he offered.

They heard explosions and turn to see the Demo retreating. "There coming lads. I need a medic."

Engineer pulled out his pistol. He also took out Mercy's blaster. "Here you go partner. Ah hope ya don't mind but I made some improvements to it."

"I don't plan on using it anyway." she said as she took out her staff. She turned to Demo whom was within gliding distance. She flew over and began healing him.

The guards came around the corner, Engineer's sentry picked them up and began shooting them. The rockets clearing the first group with ease. Sniper picking out the stragglers and the ones that stayed behind the main group

"Incoming!" Enginer said as he took cover behind his dispenser, using it as cover. Demo began shooting sticky traps to the door frame. When the next batch of guards arrived, they were promptly blown up by the bombs. The rest of the guards began to space out and started shooting back at them.

"What would I give for Medic's kritzkrieg." Demo muttered as he sent another 2 grenades rolling down the corridor he was locking down. "Could have used 1 bomb only instead of 2."

The whole time, Mercy was behind a panel of metal out of sight. "What's that?" she asked from behind.

"Something that Medic can do to make my weapons make bigger explosions. They're more armed than I expected. I just saw a rocket launcher." he ducked as a rocket sailed over his head.

"I can do something like that." she said as she engaged her damage stream on him. "You are ready to do some damage."

Demo felt his grenade launcher becoming electrified. Though it wasn't as intense as Medic's one but he could feel it. "Ehh..he he." he laughed as he shot another grenade. The resulting explosion instantly gibbing the guard. Just in time too as he was aiming it as Engineer's sentry which was busy engaging another batch of guards.

A sniper however managed to sneak around and was now flanking them. He saw Mercy hiding behind the panel of metal. He took a stand and lined up the shot. However, Engineer saw it and shouted a warning out. "Behind you Doctor!" he said as he took out a radar gun.

Mercy heard the warning and quickly flew towards Engineer, hoping to lose the shooter. The shot rang out and missed her. By then, the sentry gun had shut it's auto-target feature and had a bright laser emitting out in front of it. Controlling his sentry, the engineer quickly mowed down the flanker by using his sentry to fire on him. "This thing ain't on autopilot son!" he taunted.

Their line held. Soon the rest of the team made it back to the train yard. Admittedly, they had a better time due to numbers and that most of the guards they encountered were still arming themselves. Well, that and they had Pyro. A warehouse on that side of the base was currently being burnt down due to her.

"That was so fun. Didn't you guys see how all those chuckleheads kept missing me. And I ain't even winded." Scout was boasting as the group came into view of Engie's sentry nest.

"Gaah. You fight like a bird. All fly, no kill. Get a real gun and fight like a man next time instead of being a burden." Soldier grumbled.

"How is little angle, Engineer and Demo doing?" Heavy asked . "Good fight ya?"

"Ye right laddie." Demo said as he took a swig of his scrumpy. " This girl here bloody brilliant. She got one of everything. Even Medic's kritzkrieg. I couldn't have blown all of those people up if it weren't for her."

"I'm glad it helped. But I'm still opposed to the amount of killing that just happened." she said looking over the parts of the expired guards.

"You will have to get used to it laddie. Now that ye with us" Demo said.

The sound of spy uncloaking drew everyone's attention. 'Well, this was a successful mission. I already taken out the rest of the guards." he announced, suit having a few bloodstains here and there. "For your first time with us Doctor Zeigler, you done decently."

'Well, time for us to get out of here then. It's up to that client to claim this place by the end of the day." Engie said and the team agreed with him. They headed towards the truck and piled on heading towards their base.

By late afternoon they arrived back at base. Immediately, Spy went to the side to report to Miss Pauling.

Mercy got off the truck and she was cornered by Engie and Medic.

"Would you follow us partner?" Engie asked.

She looked at Medic, who gave a short nod. "Ok. Where are we going?" she replied.

"To discuss something. But first we need to show you your room." Engie said. "Come on partner."

They headed into the base. After a few minutes, Engie stopped at a door and pulled a key out to unlock it. After the door opened, he passed it to Mercy. "Here's your key. I hope you find the place adequate. Water's scarce and we ain't got heating unless you ask Pyro to help you and ah wouldn't recommend that." he said.

The room in question was sparsely furnished. There was a bed, a study corner. Seating for 4 people, A door that led to the bathroom. There was a closet with an armour stand next to it. A small weapon rack was next to the stand

Engineer saw her looking at the armour stand and said. "I hope it can hold your armour. Can't build an exact one just by eyeballing. Also, I assume your gear would need to be charged so I made a charging port for them. It's on the rack there. If the power isn't strong enough, let me know, I'll work something out."

"It wonderful. Thank you so much for your hospitality." she said.

"No problem. I already learnt some new things from studying your future weapons." he said. "Now another thing." he motioned to Medic who closed the door behind them.

Both Medic and Engineer pulled some chairs and sat down. "Angela, me and Engineer chatted on the way back. We were thinking of trying to sending you back to your time." Medic started.

"You can do that?" she asked. This was way more than she had hoped, she expected to be stuck here forever.

"Ah, can't make any guarantees but we can try. Only thing is it will take a while and will require a lot of resources and we ain't got everything. So we are wondering if you are willing to work with us till we can send you back." Engie said.

She hesitated there. One one hand, they were her only possible way home. But they were mercenaries who killed for a living. And they had done it for a long time if their reactions to killing was nothing.

Medic was looking at her and could see that she had trouble deciding. "We won't make you kill anyone. You just need to be our team's second doctor. I managed to keep them alive so far after all right? Should be easy for you."

"Can you promise that?" she asked

"I promise." Medic said

She looked at Medic. He seemed sincere. Hesitating, she said: "Ok. I'll join."

"Wonderful. So, how would you like us to refer to you as? While in the battlefield." Engineer asked.

"Call me Mercy. That's my callsign." she said.
