For explanation, we turn to Kevin McKidd: “They are building toward a big Christina and Owen story in the second half of the season, which will be a different story, but they are still figuring that out. But things never run smooth for Christina and Owen, lets put it that way.” Bonus: You know all the disaster training Owen has been pushing on the gang? Well, it comes in handy in episode 11, which is a “very intense and quite dark but very uplifting episode,” McKidd reveals.
