You know that poor guy under quarrantine for the first time in a bazillion years due to his particularly infectious and deadly strain of TB?
His father in law is one of the top TB researchers at the Center for Disease Control and Prvention in Atlanta.
He either:
1) hit the medical lottery to have a father in law who just so happens to specialize in the disease he contracted.
or
2) made the mistake of discussing his and his wife's hobby of "light B&D and assplay" in front of her parents.
I'm thinking closer to 2.
