I love that series, have been following it for the past 3 or 4 shows. Anyway..
the most recent one that aired here involved someone who needed a kidney transplant to get better. The guy didn't get put on the donor list for reasons that don't matter here. His wife said: run a -*test*-('"), you'll see we're a match. Turns out they are indeed a match, however, they find out that she is pregnant and because of that cannot be a donor.
So... she is her husband's only chance of survival, but because she is pregnant she cannot be a donor. She goes and will have an abortion (against the husband's wishes by the way, they have been trying for a really long time) so she can be a donor.
Who would you pick, baby or hubs, and where is your tipping point?
For the males: pretend you're the sick guy
