I guess I missed that part but uh..wait, if I was standing a half kilometer away from you..would you even be able to see me? Would I be able to see you?
I guess I just figured it was some reasonable distance like 100 feet, but half a friggin kilometer? I'd be curious as to the rationale of that distance.
Now it suddenly makes A LOT more sense to have people claiming certain bricks could react to a speedster.
