There's a big difference between personally having a miscarriage and losing a baby through miscarriage. Note the difference between how Callie and Arizona reacted when Arizona had a miscarriage. They both lost a baby, but Arizona had the burden of her body betraying her (after a year of her body betraying her because of her amputation). If Arizona had to go through that experience again, those hormones, THAT would push them over the line. Miscarriages can be really hard on a marriage.

It's possible that it was meant to be in the premiere, but they re-wrote it because there wasn't space for it.
