Jane?!

Okay, well, in Breaking Dawn it says that Alec is thêm powerful than Jane because she can only attack one 'person' at a time where as Alec can make thêm than one person 'blind'.... But then, later on in BD, when they're in the 'fight' (It's sooooooo not really a fight) Bella says (first pg of Chpter 38. Power) '...a dozen pointed attacks hit in a một giây stabbing all over the elastic shield, aimed at twelve different bright spots.' What I don't get is can Jane only attack one person at a time hoặc thêm than one... hoặc were the 12 attacks Chlesea trying to break the bonds?? xXx
