And now, on to one of the more contentious parts of the season 15 premiere trailer: Meredith and DeLuca's hot and heavy hookup. "Listen, they kissed at the end of last season. I was rooting for them before they even had that weird, awkward kiss," Luddington admitted. "So I'll just say that I'm rooting for them. I think there was definitely some tension there. What you see in the trailer there are the little looks! They're present. I know. But that's what I love about it."
