Hafidha and Frost

[Cal]

Just had a thought.  We know that Hafidha thoroughly dislikes Dr Frost (no evidence on whether Frost likes or dislikes her back, though she's aware that Hafidha dislikes her).  We also know that Frost is an oncological pathologist when she's not doing autopsies for the WTF - specialty brain cancer.

And there has been some speculation that Hafidha's traumatic illness might have been a cancer of some sort.

Is it possible there's a connection there?  That Hafs knows Frost through her diagnosis/illness, or that Frost recognised her patient for a beta and outed her to Reyes?  Or...erm, this is a scary thought...that Frost or matters related somehow triggered Hafidha's conversion to beta?

H'm.  ~ponders~

And if not, why exactly does Hafs dislike Frost so much?  Besides the obvious, of course.
