You can have more than one person die we don't even have confirmation who might die i'm guess it will be Ezra, Mona, Jason maybe Mary Drake but Jason comes back in 7x19 i believe and I think that is where he goes out at then again I could be wrong and Ezra does not die
their is all rumor of a second wedding in the finale maybe I can't see Aria getting marry twice in the finale so maybe spoby or Emison idk unless their going to let Caleb and Hannah have a offical big wedding in the finale
