@Spidy fan 2009 Yes I agree. Hell to the NO mindflayer was big boss 2 seasons str8 an then we find out its being puppeteered by a literal human from literal earth like wtf. Sidenote, S4 of ST came out directly before Disney+ series Ms. Marvel therefore Stranger Things had a "mutant" (Henry) in it's continuity before the MCU (Marvel Cinematic Universe)!!!!
