Saul and Tanya... Family Immune?

[Pandora]

I don't think Tanya or Saul are immune at all. Tanya's extreme reaction to the examination was because of her experiences at the Colony. I believe that Tanya was going to be banished/executed from the Colony. They were going to kill her because she had bite scars.

Tanya is a veterinarian. I would think that throughout her career, every once in a while she would be bitten or scratched and that would leave scars. Tanya must have been examined by the Colony and been marked for death. The only thing that saved her was the Colony's need for medical personnel.

What would happen if Fort Irwin or the Commander found out that Tanya had bite scars?

Soooo...are you still sticking with her not being immune, after todays episode?
