Hello everyone! This is a prompt I've been working on for 93MANIAC. Was trying to get this pushed out a little earlier but my dog did not take to his vet visit too well and has not been feeling the greatest so this got pushed back a couple days.

Anyways, it is an AU Mercy/Tracer story that explores on what if Tracer never joined Overwatch

Please enjoy and remember, I do not own Overwatch, Battlenet, or anything!

Chapter 1: Cheers Love

Lena Oxton was glancing at the security cameras with practiced disinterest before turning back to her phone to watch videos. Everyone had wanted to go see some famous doctor that was going through the airport, but Lena was not interested. Things outside of what would influence her life was just of no interest to her. Even when people were gushing about Overwatch, the brunette rolled her eyes. She had been given the chance to fly with them but her family had pleaded her not to. Her parents had begged her not to join as she had an aunt and uncle killed by an Omnic and they did not want to lose their only daughter. "They're being painted as wannabe vigilantes anyway," Lena had uttered in fake annoyance.

Part of her wished she had joined however. She loved flying and taking a grounded, safe job was depressing. She wanted to follow her dreams but sometimes, priorities had to change. If it kept her mum from having a heart attack whenever she wished to go to work, she was willing to not sit behind the pilot's seat despite being certified and perfectly able to. The money was not too bad either way. She heard being an Overwatch agent paid well but safe money was good money too, even if not quite as much. Even when her father died of a heart attack and her mother of a broken heart a year later, she could not muster the will to try to join Overwatch. They would roll in their graves at the thought.

Shaking her head to clear the thoughts, she sipped at the tea she had in the room and sighed as it helped. The caffeine made her hum happily as she checked the radar. She frowned slightly seeing a plane was approaching and upon accessing the satellite imagery, verified there was a plane heading towards the airport at a speed and angle that could not misinterpreted for another port. Lena then quickly peeked at the aeroplane schedule and frowned. Wait... there isn't a plane scheduled to descend for another hour. She radioed the plane and frowned as the connection was established. "This is Lena Oxton. I'm in the control tower of this airport. Is there an emergency causing you to land?"

"Nothing of the sort," a dark hiss sounded. The voice perturbed her for some reason and made her think of metal being scraped alongside metal. "Just bringing you some mercy."

"What is he..." Lena muttered as the connection got cut. She glanced towards the cameras and her eyes widened. Was the plane really that fast? What is going on? She glanced up at it and then gasped. Shite! Got to get out of here. She reached for the door and frowned as she tried to open it to no avail. Cursing, she reached for the biometrics panel and received a blank beep of rejection. "What is going on?" She peeked at the security cameras and saw how the other employees were still around the Overwatch agent, happily talking to her, blissfully unaware. Reaching for the radio, she cleared her throat. "Could one of you loves let me out? We kind of have a situation here!"

"Lena, is it really important? You sure you just don't want out of the room since at least one person needs to be in there at all times?" she was teased but the brunette was getting frustrated.

"We have an unauthorized plane on a crash course," Lena snapped and her backup security card failed authenticating on the security door. "And my credentials are not letting me out the door."

"Alright Lena. I'll try to get you open," one of the security guards chuckled as they hung up the radio connection.

The young woman though was antsy, her eyes focused on the monitors showing her how close the aeroplane was. It felt like an hour later even though it only was five minutes when she heard noise outside the door. "Hello?" she asked hopefully.

"Lena, what did you do? This door won't open!" the guard called back in response.

It felt like ice water was in her veins as she remembered the mysterious words over the radio. "You guys need to evacuate the airport!" Lena yelped in panic. "There is an aeroplane on a crash course!"

"Lena, you're just panicking. Just relax and..."

Cursing, the young woman reached for her cell phone and took pictures, immediately sending them to the guard. The response was immediate. "I need all non-essential personnel to evacuate the area. Immediately!"

Lena breathed a sigh of relief and slumped on a nearby chair. She did not bother trying to break out as the room was specially reinforced to protect the people within from external threats. She would not be able to crack the glass or break down the door with minor firepower. She poured herself some tea and glanced over the security footage. While she noted that the normal people who were merely waiting for flights and the workers of the cafes were leaving, of course the port's personnel were stuck. What caught her eye was a haunting pair of blue eyes belonging to a blonde woman. Her clear glance was poised and refined but there was a hint of kindness in the orbs. "She looks too good to be true," Lena muttered softly as she looked at the plane's location. "It's odd. She almost looks like an angel." Her eyes closed as she could hear the panic now. People were screaming to get out of the area and she was stuck here, oddly calm and resigned to her fate. "Why is she still here, I wonder?"

She watched the woman reach for one of her packages and pull out a metallic suit. Another package had a staff which the woman wielded with practiced precision. Glancing up at someone, she appeared to take flight as she went to assist people. Lena watched the mysterious woman fly people to safety.

"Curious. How can she remain so calm and collected during a crisis?" Lena muttered as she glanced. The plane was now visible and Lena sipped her tea. "Gods, how am I so calm?"

"Lena!" voices roared from outside the control room. "Lena!"

"It won't budge. You lot know that," she responded blankly. She drank more tea and wished she had something stronger. Like a whiskey. "It's been nice knowing you all."

"Lena! You act like you're going to die," a few of the employees trapped outside were crying and she smiled.

"You need to escape. Look for me afterwards. Then I can see you all and think, 'Cheers, love! The cavalry's here!'"

"Young lady, you're very brave," a clear voice called out. Lena frowned trying to place the accent but could not decide between German or Swiss. "Please know that afterwards... we'll find you."

Lena smiled. "Just... save the others." She could see it easily now without squinting. "You have time to escape now. Clocks ticking." She must be that Overwatch doctor they were talking about later. Pretty sounding bird, that.

Lena heard the woman's voice attempt to reassure her. "Heroes never die," she vowed before leaving. The young woman could practically hear the footsteps reverberate before heading over to the radio. She contacted the plane and was greeted with an amused hiss.

"Yes?" the voice felt like it had the darkest, biggest smirk Lena had ever heard.

"Get stuffed. You won't be killing hardly anyone today, bloody terrorist. Trying to take out as many people as possible is rather cruel but we stopped you."

Raspy laughter sounded over the radio. "I wasn't looking for body count for once. But I will take out Mercy."

"You aren't making any sense! You know what? Get stuffed!" Lena shouted over the radio before looking up. She headed towards one of the closets and tried to brace herself. Despite the bravery she displayed to the mysterious man on the radio, she was frightened. "Mummy... Daddy... I don't want to die," she whispered softly. When the plane impacted the control tower, she did not get time to think as plane plowed through the room, straight into the closet, taking her with it. The intense pain made her black out and her instinct was the curl up, hoping nothing would damage anything vital.
