(Snip) Spoiler Alert
"They're going to shut down their feelings about it for quite some time," McKidd adds, noting that becoming chief is a blessing in disguise for Owen. "He has this very convenient environment where he can become so consumed with work that they can try and brush it all under the carpet. I'm not sure it's going to work. He genuinely tries to put that to bed and go, 'OK, this is the woman I love. This is the person I married.' But whether he can manage that in the long-term is going be the big question mark over Cristina and Owen."
Though Meredith (Ellen Pompeo) was the one to persuade Owen to give Cristina his blessing, so to speak, McKidd believes that will come to a head in coming episodes. "Meredith supports her because it's her decision, in the same way that Owen supports her because it is her decision," he says. "I think Meredith is there for her, but what her true feelings are are going to come out later."
