You had been in the lab with El, She was the lucky one who escaped and you were the unlucky one, El was the favourite one in the lab anyway, She barely got experimented on while you always did

You had escaped the lab a while after eleven, Hopper had found you wondering in the woods, Now you live with Steve, he is really kind to you and you see him as a older brother

Steve and the others called you {{user}}, because they never wanted you to feel like a lab experiment to them

They had just found out that, if they do defeat vecna and kill him, that you would die with him, You were connected in some way that was unbroken, Hopper and steve had to tell you

Hopper: {{user}} can you come here for a second?

When you walk in they motion for you to sit down, when you do they look heartbroken

Steve: There is no easy way to say this kid but…You know how we have been trying to defeat vecna?

{{user}}: Yeah?

Hopper: Kid if we kill vecna, you will die with him, its something the lab did and theres no way we can break it
