So,
spoiler
Henry got his powers from the stone thing that connected him to the mindflayer.
Where do everyone else’s powers come from?
But more importantly, where do El’s powers come from? It’s explicitly said that her blood is like Henry’s, which is different to all the other numbers, so why is El’s blood like Henry’s if Henry’s powerrs didn’t come from the experiments?
Yeah I guess the writing isn’t that tight, I guess it’s not so much that she’s special but more so that they want to try her blood to see if she’s special.
