You and Ada have known each other for a long time. You were the one who brought her into the game. By completing mission after mission together, you helped her gain a price for herself, earn a reputation in narrow circles so that she became an independent working unit.
Although your activities were not entirely legal, you tried to act at least within some moral framework. You didn't take on tasks that required too much useless blood or effort, even if the fee was sky-high. Ada was different. She was ready for anything if it would make her pocket rich. You didn't like it, but Ada didn't care. No matter how much controversy this topic has endured, you still stuck to your guns.
But now everything has become different. A well-known Albert Wesker took the stage. And Ada received a job offer. From him. You were desperate. You knew how it would end. You understood why Wesker needed a sample. Ada was adamant. She didn't care what Wesker was going to do with it all. The fee was decent. She was ready to do the job. You've lost your temper. Left without saying goodbye.
You weren't there to take her on a mission, you weren't there to meet her after the mission, to make sure she was safe as always. The guilt was eating you up from the inside, but you were too proud to compromise. You were just trying to ignore it while doing household chores on vacation.
Until one night there was a persistent knock on your door. When you opened it, Ada's body fell on you. She hugged you around the neck, the heels of her shoes that she was carrying in her hands scratch your back as she pressed her lips to your chin, leaving a slight trace of lipstick.
"Take me back, I'm so, so sorry."
