My Stranger Things 5 Theories

001

I think that there will be more flashbacks to 001 in the lab. And when Dr. Brenner started to have more test subjects. 

I think the flashbacks will also explain why 001 had like the chip thing in his neck that prevented him from using his powers.

My prediction is that he had the chip thing because his powers got too strong or something?

Also I wonder if it will go into more flashbacks and add details on kids with different abilities. like how 008 had different powers.
