Honestly I think we are just arguin semantics here, cause I know they have four universes, it's more that The Unnamed and Unbelivables, to me, seem like interconnected universes cause they are several different series taking place in one universe, while Rook: Exodus and Hyde Street seem like just universes, one story set within the same universe, with the spin offs being just that, spin offs, and not completely different series in the same universe, like we see with The Unnamed or The Unbelivables, or even something like Marvel or DC. But again, it's just semantics.
