I just saw disc 4 and...
AAAAAAAARRRRGGHHH! How could they do that? They can't both be dead! And that crappy Frost guy isn't cool enough to have killed them.
It's just not fair!
... And I'm somehow hoping that they could somehow do some miracle lifesaving surgery and save both of them, like they did for Noelle.
It's just so not fair! *sob*
