I must have misunderstood the situation with the upside down being a wormhole, thank you for that. I still think that their powers should have disappeared after the mindflayer died. The way I understood it as it was presented in the show, the mindflayer became a part of Henry. If they used his blood to create more psychics they would have only spread the mindflayer’s influence. If it’s explained better in the play then great. Still though, there’s a lot I didn’t like about the last season. Like I said though, it wasn’t a bad ending things just didn’t add up for me.
