(Tell me if your oc is SCP or scientist (( yes, they can be hybrid)) and explain what they do)

1.) (If you choose to be SCPs)
You're SCP-(whatever number you are), you were born and raised in the labs like some of your friends.
You would have call this home if they didn't torture you with experiments and tests. You would leave this horrible place if you could but you unfortunately can't since your and the others parents are lock up somewhere in the building, you rarely get to see your parents and it honestly hurts you when seeing them in straight jacket, being hold down by chains.
But there's nothing you can do to help them.
The only good thing you like about this place is that you're not the only kid here and that one of the scientists are kind to you (that is if Tord or Edd are your parent).
Alright now, you were hanging out with one of your friends in 'play room' (it's the only place you can quickly have fun without being experience on besides the cafeteria). As one of your friends talked, you couldn't help but notice some people though the window were talking to a scientist about something. When you got a better hearing, you were shocked to realize you and one of your friends are being sold off to army as a weapon (or slave)
What will you do...?

2.) (If you choose to be scientist)
Today is the day! You get to go to work with your parent like you always wanted.
Since today is your first day work at the labs, your parent is your tour.
They started showing you around, you were a amazed by everything they show you.
You soon noticed there was a big window, curious you walk over to it and look though it.
You never thought you'll ever met any SCPs nonetheless a kid one.
It honestly amazed you but... You couldn't help but notice that some of them... Looked miserable
... What will you do?
