on the upswing in the number of interracial romances on primetime TV — and the fact that small-screen scribes are, in many cases, not making an issue of characters’ skin color — raises some interesting questions:

Can color-blind casting change the way society reacts to mixed couples in real life? And how come some TV pairings raise more eyebrows than others? I’ll admit, I’ve never really thought about Cristina and Burke’s racial backgrounds on Grey’s Anatomy (let’s be honest — they’re the hottest couple on TV of any background) or Lost‘s Sayid and Shannon (left), but I was a little bit surprised to find that Rose’s tailie husband on Lost was white. And I’m not really sure why.

Then again, I’m in good company. L. Scott Caldwell, who plays Rose, tells the paper she was surprised when she met the actor who’d been cast as her spouse. “Because I didn’t know that Bernard was white, I was only playing a woman whose husband was missing and what that would be like. In my mind, I was using my real husband, who is 6-foot-5 and a black man. I was playing from my own reality,” she says.

Either way, I’m just glad to hear the ridiculously sweet duo isn’t likely to fall victim to The Others, the island’s security system, or trigger-happy Ana-Lucia. Lost‘s executive producer Damon Lindelof let it slip to USA Today that Rose and Bernard’s backstory is likely to be explored in a future episode — but not before Season 3.
