My karma is neutral and when I go and talk to her she calls me an [censored] and goes through with that dialog. WTF I thought she got angry when you are evil not neutral.

if you want her to shut up about your karma, *introduce* her to Mortimer.

Odd.

How's your NCR rep doing?

edit: I ask because that's the only thing I can think of. I believe Cass is NCR... and that *might* have something to do with it. Then again, it might not.

I'm on good terms with the NCR.

Hmmm, is this the first time you're meeting Cass? What have you done with her so far?

I think your karma may still show as neutral if it's in the low negatives. You don't actually see your "karma points".

Kill a couple of Ghouls or Fiends, get a positive karma, talk to her.

I now have good karma and everything is peachy with her. I just don't recall her getting bent out of shape when you are neutral.
