Aaaagh!! I hadn't even considered them killing Nat off D: Now I'm super nervous for the movie :X

Nobody is going to die in this movie. Not permanently. Not when everyone in the original cast has at least two and possibly more movies in their contract. That would just be dumb on Marvel's part.

There are rumors about literally everyone dying and rumors about literally everyone being in Cap 3. I think we all need to just chill for the time being.

Hear, hear. Just because it's Whedon directing doesn't mean he can go and kill off favourite characters from a franchise he doesn't own.

If a major character disappears under a pile of rubble he/she will be back for Civil War, as the deus ex machina when all other hope is lost ...

thank you ^^
