Hello? Is there anybody in there?

I just watched Blade Trinity again (thanks Kim). Its not bad. As I have said before, "just the right amount of cheese". Just like Pitch Black/Chronicles of Riddick. Every now and then, you need a bit of that. But not too much. Damn, take it back.
Seriously though, what was up with the blind chick? You know, the one who was also annoying in American Pie? Why was she blind? How did that enhance the plot? And how many blind bio-chemists do you know who use a computer? All of her information was non-brail text. What possible use would that be to her?
Ah, plot holes.
