'Grey's Anatomy's Kelly McCreary Dishes About How the Maggie-Jackson Romance Happened

A new love triangle is forming on Grey's Anatomy and actress Kelly McCreary is dishing on the potential romance between Maggie and Jackson.

Even though Maggie (McCreary) and Jackson (Jesse Williams) have been friends for much of their time at the Seattle hospital, there seemed to be sparks flying between the two in the season 13 finale.

"I had heard whisperings of it, but it took a long time to come to fruition and it kind of came out of nowhere, as much as for us actors as it did for the audience," McCreary said while talking with ET.

"But I think that's true of some of most beloved storylines on Grey's came out of nowhere: long-lost siblings that nobody expected and nobody knew existed, love affairs, sexual awakenings, all kinds of things," she added.

"I think that often the surprises, whichever direction they go in, they really serve to keep the stories rich and interesting, and the audience loves them, whether they think they knew it first or not," McCreary continued.

When directly addressing the blossoming relationship between Maggie and Jackson, McCreary remained coy.

"Maggie and Jackson have a lot of interesting points of connection and whatever winds up happening between them, whether it's romantic or not, we haven't really seen them engage that much as characters," she said. "That'll be a great way to get to know each of them, to get a little bit more into their psyches and their histories and their desires and what makes them laugh and just get to know them a little bit better."

In the finale, Jackson's ex-wife and mother of his child, April (Sarah Drew), made the observation that there could be a potential relationship between him and Maggie.

If a relationship between Maggie and Jackson plays out, McCreary is excited about the possibility of working with Sarah Drew.

"Anything that gets me more scenes with Sarah Drew, who is one of my very favorite people on the planet, I'm happy to do it. I have no idea that's going to go in, but those are two more characters who have not had a lot of meaningful interaction and this might really give us a chance to get each of them differently and better," McCreary said. "I think it's just ripe for a lot of really great possibilities."

Grey's Anatomy kicks off season 14 with a two-hour premiere on Thursday, Sept. 28 at 8 p.m. ET/PT on ABC.
