Anything for Will (Will Byers x Twelve)

Twelve and Eleven have been stock in the lab since they were born. The twins want one thing: to get out and escape from the bad men. The two girls have abilities and are some kind of weapons. Dr. Brenner wants to keep them to himself and continue exploiting their abilities. When they finally reach their goal what's next? What will they face?

Twelve sees a cute bowl cut boy running for is life in the void and since then she has a strange connexion to him.

Eleven and Twelve don't know a thing about the "real" world or close to, but they know one thing: together they can face anything.

I obviously don't own Stranger Things, but Twelve is my character. At least, this version of Twelve because some people have their own version.
