There are fears that one of the couples on 'Grey's Anatomy' may not survive a major challenge in their relationship.
Warning: major spoiler alert!
In the most recent episode of the new series on US television, fans saw Callie (Sara Ramirez) announcing that she planned to move with grant winner Arizona (Jessica Capshaw) to Africa.
Viewers saw Callie struggle over whether to tell Arizona her real feelings about the move.
Actress Ramirez told TVGuide.com: "Callie [was] caught in that thing where you love somebody so much you don't want to tell them the truth.
"Callie really doesn't want to go, but in order to be with Arizona, they decide to go together."
She continued: "It turns into a very rough road. Because Callie wasn't very honest from the beginning, it bites her in the butt. She ends up having to be honest about the fact that she really doesn't want to go to Africa, but she's going to go anyway.
"Arizona and Callie find themselves at a crossroads where Arizona isn't too thrilled with the way things have gone down, and once again we find ourselves at an impasse where we're not sure if they're going to make it."
