Perhaps if you say certain things, Duck becomes infected and bites Katjaa, and then you have to finish them both off?
This is all theory though, I've got nothing to back it up. :P
Jokes aside, it could very well be the case that previous mentions did indeed indicate that it was possible to prevent her "suicide" yet not, ultimately, her death. If true, that's rather sad. She was, non-romantically, the kindest woman in the group and loosing her life as she does is tragic.
