Fear not! My sense is they are one of Shonda's favorite couples too, and although she told us Cristina and Owen will get "darker," she said that is "before it gets better." It gets better, people! Also, you can bet good money those two will keep sharing lots and lots of screen time for as long as they are both on the show, because, per Shonda: "I've been having the time of my life writing for Sandra [Oh] and Kevin [McKidd] because honestly it doesn't matter what I write for them, they hit it out of the park. It's amazing."
