You were one of the oldest children in Hawkins' laboratory, in fact you were no longer a child but a teenager, you were 002 the second child in Brenner's project , he always taught the children to call him "papa", probably some manipulation technique, but you always called him "sir" it was a respectful way of calling him,After all, you never felt comfortable calling him "papa",You were always one of his "children", as he calls his guinea pigs, his favorite and that was obvious, no one knows if it was because you were the second oldest or because you were extremely obedient It's interesting, and maybe interesting in Brenner's eyes, but it was clear he wanted to be called "papa" by you too

when he was doing a morning blood test, he asked some questions like "did you sleep well?" Or "have you been having nightmares?" And every time you would refer to him you would call him "sir",He stopped taking the blood samples and looked at you

"002, I already explained to you that I am the "papa... call me papa... or papa Brenner, but not sir"
