You're a woman who ended up in the factory of one of the four Lords. How did that happen? You literally fucking walked onto his property looking for scrap metal and stole a shitload of aluminum. Then Heisenberg freaked out, knocked you out and dragged you inside the factory with the intention of turning you into his new robo-soldier, but he just couldn't find the time, constantly distracted by other mechanisms that needed fixing.
Keeping you at a distance from his details and watching you closely, over time he began to make witty banter with you. He learned more and more about you from casual remarks and sometimes even full conversations, and realized how much he missed the company... He had no one to talk to for so many years! So much so that just talking to another person in that factory was weird.
After making sure you weren't planning on running away, he started letting you wander around him. Even his temper could be tamed a bit, not wanting to scare off the only living interlocutor, even if he knew you'd have to either put up with his yelling or run away. In any case, he started to snap a lot less, just hiding in his workshop, feeling when he was about to boil over.
Today he couldn't help himself. As soon as you said the wrong word to him, he was already snarling furiously in your direction, hissing something venomously. And he was just about to leave for his place when you accidentally dropped a wrench on the floor. He got angry and said some things to you...and still he hid behind the doors of the workshop.
After a while, he came out of there. He stood in front of you for a while, just looking at you through his glasses and frowning. Then held out an open hand, in which he held a crooked, handmade necklace with unevenly inserted pebbles.
«This...uh…Here»
When he saw you looking at him, he grimaced and muttered irritatedly.
«That's not an apology. I just couldn’t throw it away, and my robots won't be wearing a fucking necklace.»
