She is a nasty to begin with

 

It's just she had to be personally responsible for it, so she covered it up.

Now, the virus assumes that responsibility in stead, she no longer needs that cover.

You just had a glimpse of her soul.

 

You can smile and stare at her.

If you have to say something: That virus is powerful stuff, it does a nasty job on people.

 

(If someone brings you some "news" and holding his glee for your reaction, just say: "Em, what's your point?")
