If the volturi attacking Is Alice's vision how could she see?

I don't know how she can suddenly see the Người sói hoặc Renesmee - it's quite a major plot hole (though admittedly it is my favourite scene in the whole movie series).

Because she can see the volturi's desion because they are ma cà rồng and the warewolves aren't a part of the decion.

It becomes True duhhhhhhhhh

There must be enough ma cà rồng present for her to see the event despite the holes in her vision caused bởi Nessie and the wolves. And the important decisions were taken bởi vampires: first Irina then the Volturi.
